Five Ponds Wilderness - The High Falls Loop

The people of the State of New York claim ownership but make no mistake, the Five Ponds Wilderness is the kingdom of the Beaver. That's what makes Five Ponds so great. It's real wilderness: wet, muddy, buggy, overgrown and generally inconvenient.

I recently (Sept 2015) hiked the route known as the "High Falls Loop". With a couple of short side jaunts that hike covered 17.1 miles; very close to my limit for hiking miles in one day. There are challenges, and the general messiness that defines the place, but Five Ponds is also an uncommonly flat area. The elevation differential between Cranberry Lake and High Falls is just 100 feet and the area's defining feature, the Oswegatchie River, follows a meandering path through a broad valley. Long stretches of the trail follow a track originally built to support a logging railroad and that solid base makes for fast and easy walking.

The yellow line shows the trail south to the five small ponds after which this area is named. The gray lines show the routes of historic trails abandoned following the 1995 storm that caused extensive blowdown throughout this area. (Image capture from Google Earth)


The Five Ponds Wilderness is all about the water. There are lakes, ponds, streams and the Oswegatchie River. Then there are swamps, bogs, and marshes of every size, shape and variety. And if that's not enough there are Beaver ponds at every possible stage of succession. 

A wet meadow. The Five Ponds area is noted for its' open meadows including the large open area known as "the plains." The plains is classified by the New York Natural Heritage project as a boreal heath barrens; an uncommon ecological community type. The area pictured is a wet meadow just north of the plains. 

High Falls on the Oswegatchie River. This is the falls at a time of very low water. August and early September 2015 have been unusually dry.

I started the day heading south on the High Falls Loop East Trail. This popular trail connects Wanakena with Janacks Landing on Cranberry Lake and it provides access to various trails and destinations in the northeastern quadrant of the Five Ponds Wilderness. It is also the shortest formal trail to High Falls. The route covers 6.1 miles to a trail junction where you follow a half mile side trail to the falls. A sign near the falls reads "Wanakena 9 Miles". That's the distance if you return by continuing around the loop on the west side trail. Which is what I did. The two trailheads are less than a half mile apart on South Shore Road in the Hamlet of Wanakena so the loop hike is easy to manage without the need for two cars.

As mentioned, a good part of the route follows a grade originally built to support a railway. The rail lines were laid just after the turn of the 19th century by the Rich Lumber Company to enable timber harvesting on the 16,000 acres the company owned south of Wanakena. I haven't seen references to exactly when the rails were removed but the state acquired the land in 1916 and it's likely that the company took the rails with them when they departed. By that time the forest had been heavily logged and intense fires had swept the area. Much of the High Falls Loop trail passes through a second growth forest that is roughly 100 old. After the state took ownership of the land the railway grade was converted to a truck trail. That woods road was abandoned when the Five Ponds Wilderness was created and and the route became the west side trail.

Along with the falls, a highlight of the trip is the unique ecological area known as "The Plains"; a large open area that was present before the logging started. The Plains is classified by the New York State Natural Heritage project as a Boreal Heath Barrens.


Looking into the "plains" from the south. An uncommon combination of environmental and ecological factors has apparently kept this area from being reclaimed by forest. At least at the rate that might be expected,. However, it seems likely that over a longer period the trees will recolonize much of the area and the plains will fade into the surrounding forest.


As mentioned, much of the route is on a relatively smooth and level trail that makes for fast walking.
But there is one recurring challenge. The route has recently been flooded --or currently is flooded-- by beaver activity at more that a dozen locations. The wetter terrain lies mostly in the southern half of the route but the one place where I was not able to avoid wet feet is less than a half mile from where the west side trail joins the road in Wanakena. The trail crosses over a slightly raised causeway between a swampy area and a made-made pond and Beaver have damned the culvert that allows a small stream to flow through. The result being that the causeway itself was completely flooded (Image 4). Short of backtracking and bushwhacking around the entire mess there was no way to avoid walking through the water. Given that I had already walked over sixteen miles, and that I was ready to be done hiking, I just plowed on through. Had I started the loop on this trail the story would have been different. Getting wet feet at the start of a long day presents a significant problem. Looking back I realized how many places I had just barely made it through while staying dry. If you hike this route expect to do some wading and plan accordingly.


It looks like you could stay dry by walking in the grass on either side so you'll have to take my word for it; there was no way through this section without getting wet feet. A man-made pond is just out of the photo on the right and the water visible in the trail is the edge of pond backed up by the Beaver. That water is coming in from the left and the grass there stands in several inches of water.

One of the many places where the path crosses a beaver dam.

One of the reasons I really wanted to hike this route was to finally get a first-hand look at the havoc wrought by the infamous Derecho storm of 1995. That storm, on July 15th 1995, caused extensive blowdown throughout the Adirondacks and the forests of the Five Ponds Wilderness were particularly hard hit. Just over 20 years have passed since the storm and evidence of the event is starting to fade. The route passes through several areas where nearly every large tree was knocked down; evidenced by the lack of large trees and by the tangle of large decaying logs lying everywhere. Equally striking is the bright sunlight that reaches the forest floor in these places. Areas where the canopy was knocked down are now filled with saplings of the pioneer tree species that fill in whenever an opening appears in the forest.

Following the 1995 storm trail crews cut through hundreds of downed trees to reopen the trails.

The trail crosses a mud hole on this log. The log sways a bit and you need to be sure footed. It was dry on this day but this crossing could be quite daunting when it is wet.

That 1995 storm figures in my family history as well. The storm passed through just after sunrise on a Saturday and we were planning on attending a family reunion in Long Lake on Sunday. We live in Saratoga Springs and we experienced the storm as a notably severe thunderstorm. During the day on Saturday we heard reports that the storm had been much more severe in the mountains and that several campers had been killed by falling trees. Driving up on Sunday morning we could hardly help but notice the many trees down along the roads but, it was not until we got to Long Lake, and heard my Dad's story that the uniqueness of the event came into focus. Dad was then a member of a hunting and fishing club that leased the area around Rock Pond (south of Little Tupper Lake, now part of the Whitney Wilderness). He had arrived at the cabin the club maintained near the pond on Friday and planned to drive out to Long Lake on Sunday morning to attend the reunion. Shortly after the storm passed it became clear to him that that was not going to happen. The cabin where he was staying, and, his pickup parked nearby, were both unharmed, but several miles of woods roads lay between him and pavement and large downed trees lay across the entire route. I don't recall exactly what he did on that Saturday but probably got into his canoe and went fishing thinking that other club members (some of whom are also members of our family) would eventually arrive.

Instead, the silence of Sunday morning was broken by a float plane coming in for a landing on Rock Pond. Another club member had flown in to make sure he was OK and he hitched a ride back to Long Lake by plane. Hearing his tale of experiencing the storm in the forest was harrowing enough but the human tragedy was brought home when we reached the Lake Eaton campground for the reunion. A camper trailer crushed down to the axles sat forlornly in the parking area.. No one was killed at Lake Eaton but a camper did die at Lake Lila; a place where we have camped several times.

Following the storm much dismay was expressed over the loss of old-growth timber in the Five Ponds region; many large, old, trees were toppled. But storms like this have blown through the Adirondacks many times before and will continue to do so in the future. From the perspective of a human lifetime this is significant forest event and, for a few families, a deep tragedy. But in 100 years direct evidence of the event will have vanished and unless we do something really stupid the forests will go on. And the beaver won't care.

USGS Historical Maps Via Topoview

In the days before Google Earth (and similar) one of my favorite pastimes was to pour over printed maps. And my favorite maps were the large scale topographic maps produced by the the USGS, the United States Geological Survey. Back in the day we actually went to a store and bought the maps we needed and a collection of large-scale maps covering the Adirondacks was a non-trivial investment.

Going back to the mid-90s the USGS has also provided digital access to maps from its' vast library. That access has evolved considerably over the last 20 years culminating in the recently unveiled Internet application called TopoView. TopoView provides public access to (nearly) the entire library of historical topographic maps created by the agency over the past 135 years; over 170,000 map sheets from different editions (year and scale). If you want to dive right in the link goes to the TopoView home page where you'll find a short video that explains how to use the application. Or just go straight to the application and start poking around. The TopoView interface is well designed and well executed. Best of all, it's fun to use; at least I think so.

A screen capture of the TopoView interface. The box in the lower left provides details map sheets available for the selected grid cell. Clicking the map image in the box opens a high resolution image of the map. Links in the box allow maps to be downloaded in several different formats.  
TopoView is a remarkable application and, for the Adirondacks, it provides a unquie source of historical data. The Adirondack region has undergone two great transformations over the last 200 years. The first was the destruction of vast swaths of virgin forest by logging and fire starting around 1850 and lasting into the early 20th century. The second transformation has proceeded more slowly but is well underway. It is the regeneration and succession of the Adirondack forests following the  protections put in place starting in the 1890s. The maps available via TopoView provide a timeline and geographic snapshot of  that second transformation.

Let's look at some maps that illustrate what I'm talking about. The four maps that follow are:
  • 1898 - USGS 1:62500-scale Quadrangle for Thirteenth Lake. The map is overlaid with two current hydrologic data sets (also available from the USGS). The red lines represent streams and rivers and the dark blue areas are represent water bodies (lake and ponds).
  • 1954 - USGS 1:62500-scale Quadrangle for Thirteenth Lake, NY - with hydro overlays
  • 1954 - USGS 1:62500-scale Quadrangle for Thirteenth Lake, NY - water boundary overlay is not shown to make it easier to see the representation on the topographic map
  • 1997 - USGS 1:25000-scale Quadrangle for Bakers Mills, NY - a higher resolution recent map

Map 1: 1898 - USGS 1:62500-scale Quadrangle for Thirteenth Lake. The map is overlaid with current hydrological data. The red lines are streams and rivers. The dark blue areas represent water bodies (lake and ponds). The mis-alignment between this 120 year old topographic map and the modern GIS layer is clearly visible. But this map was made in the days before aerial surveys and it met the accuracy standards of the day. Quite remarkable actually, this is not easy country to move around in.

Map 2: 1954 - USGS 1:62500-scale Quadrangle for Thirteenth Lake, NY - with overlays. The modern boundary layer for the Mud Ponds aligns closely with the outlines shown on the topographic map.

Map 3: 1954 - USGS 1:62500-scale Quadrangle for Thirteenth Lake, NY - water boundary overlay not shown. Note the addition of the trail that reaches the ponds.

Map 4: 1997 - USGS 1:25000-scale Quadrangle for Bakers Mills, NY - a higher resolution recent map with water boundary and stream overlays. The current hydrological overlays align closely with the topographic map. 

I download the topographic maps using the TopoView application and loaded them into qGIS (Quantum GIS, open source GIS) so I could add the high resolution water layers that provide an up-to-date geographic context. Map one, from a USGS map printed in 1898, shows an approximation of the size, shape and location of the two ponds (Mud Ponds, in the Siamese Lakes Wilderness). But that's not to say that the map did not meet the accuracy standards of that time. Given the survey methods available then the map was very likely up to standards and accurate enough. If you wanted to visit these ponds that map could serve as your guide. While it is ultimately true for all data, geographic data is always an imperfect and approximate representation of the real world. It's easy to forget that when reading a well produced map from a trusted source. USGS topographic maps are produced to meet an accuracy standard that defines acceptable levels for accuracy and errors. You can learn more about this here.

Map two shows the same water layers overlaid on the USGS map from 1954 and, as you can see, the alignment between the USGS map and the modern water layers is significantly better. This map also shows a trail. That trail was not shown on earlier coverages of the area. Map three is the same configuration but with the display of water boundaries turned off. This makes it easier to see the ponds as they are represented on the topographic map.

Map four was made using the current base map from 1997. The newest map is higher resolution with a scale of 1:24,000. The earlier maps represented a scale of 1:62,500. The alignment of the water layers with the latest topographic map is very good. An interesting side point is that the trail visible in the 1954 map is no longer present on the map. See my post on a recent hike to these ponds to learn more about why this point was important to me.

The maps I downloaded from TopoView to create the above images were retrieved in the GeoTiff format. That format provides the highest quality option for maps retrieved from TopoView. The KML option is nearly as good and works best with Google Earth. The GeoPDF format is best if you want to print a copy of a map that you download. And the JPG option is good for viewing maps directly on your computer, especially in a web browser.

In upcoming posts I'll discuss additional opportunities and issues associated with this incredible source of historical geographic data.
