Moreau Lake State Park: Wondrous Lake Bonita Trails

It was just 24 months ago that 750 acres formerly held by the now closed Mt. McGregor Correctional Facility were formally added to Moreau Lake State Park. Since then a new parking area for hikers and three new trails have been built. That's a pretty good pace for these sorts of things but what makes this a truly impressive effort is that these new trails are really well thought out. Moreau Lake State Park now offers hikes ranging from a couple of miles to a "grand loop" covering nearly 15 miles without any retracing of steps (you can bet an account of that walk will appear on this blog in the future). My most recent outing, covering nine miles, took me past two attractive lakes, over ledges and past cascades and through an attractive and varied forests. There are good view along the way of the Hudson River and the southern Adirondacks.

An overview of the Moreau Lake State Park trail system. The heavy blue line, starting at the bottom left, is the route described in this post. The other colored lines seen on the map represent other trails in the park. For scale, the route represented by the heavy blue line covers a distance of just over nine miles. The two sections closest to the bottom of the image are new trails added as part of the Lake Bonita expansion.
The newest trail leaves the Lake Bonita Loop Trail near the spillway at the north end of the lake. From there it's about 1.5 miles to a to a junction with the West Ridge Trail. At the time of this writing that junction is unmarked but the trail itself is well marked (parking is on the Corinth-Wilton Mountain Road).

The Western Ridge Trail is one of the primary access trails that lead up onto the Palmertown ridge and the Park's main trail system. The Palmertown Ridge is interesting from both geological and ecological perspectives and evidence of the last glacial period lies heavily on this landscape. It is generally believed that the ice sheets of that last glacial period retreated from this area between twelve and fifteen thousand years ago with mountain glaciers persisting into the more recent end of that range. That's a long time by human standards but not even the blink of an eye in terms of geologic time. Walking the trails on the Palmertown ridge always reminds me of this. There are many places where soil lies just a few inches thick on top of deeply scarred bedrock.

The geology of the Palmertown ridge strikes me as being somehow different from similar landscapes in the southern Adirondacks. For example, the ridge crossed in the first couple miles of the Northville to Benson section of the Northville-Lake Placid Trail has some characteristics in common with the Palmertown Ridge. The Northville ridge is a little higher but ecologically similar; an Oak-Hemlock forest. But the landscape has a different feel. Could it be the distinction between being part of the Canadian Shield (the primary geologic formation of the Adirondacks) as opposed to rock that has been pressed up against the shield. I'm imagining that as a possibility for the Palmertown Ridge. The most likely explanation is that this is my imagination run wild. Perhaps someone with more knowledge of the geology of the region will let me know.

In any case, the terrain encountered on the Palmertown ridge is unexpectedly rugged and, according to my GPS, the total elevation gain for the route I walked was 2200 feet. There's just a single significant climb so nearly all of that elevation gain comes from the relentless ups and downs you encounter along the way.

One point of specific interest for me was a stand of spruce on the northwest shore of Lake Bonita. I had noticed the trees on my previous visit. But that was a day of our only major snow fall of the year and with darkness approaching I took no time to investigate. Still, I did notice two things:
  1. The trees were some kind of Spruce (I was not sure of what variety) 
  2. The trees looked out of place
Taking a closer look under benign conditions confirmed both points. My first impression had been that this was a stand of Norway Spruce; a widely planted import to the Adirondacks. When Norway Spruce grow in the open --as the do in various places in Saratoga Spa State Park-- they exhibit a distinctive branching pattern that makes them especially easy to identify. However, when growing close together under constrained conditions Norway Spruce can look a lot like other Spruce varieties that are native to this region. However, there is one identifying characteristic that trumps all others. Norway Spruce have long cones that are much larger than any other spruce from around these parts. These trees are Norway Spruce.

From the first overlook on the Western Ridge Trail. This popular destination is barely a mile from the parking area on Spier Falls Road. It's a bit more than 2.5 miles from the new parking area on Corinth Wilton Mountain Road. The view is of the Spier Falls reservoir on the Hudson River and the Southern Adirondacks beyond.

This open glade on the ridge line near the Western Ridge trail was probably open meadow just a few decades ago. The trees are Chestnut Oak. A common species on this section of the Palmertown ridge. This species somehow favors the edges of steep ridges. I'd love to more about the history of the forest on this ridge.
