Notes on the Tongue Mountain Range:
The last 6 mountains in this list are part of the Tongue Mountain range on the Western shore of Lake George. These can be done as a traverse from the Clay Meadow trailhead to the Deer Leap trailhead (or vice versa). Note that the Tongue Range is a known habitat for Timber Rattlesnakes, the largest venomous snake in New York. Learn more here: https://dec.ny.gov/nature/animals-fish-plants/timber-rattlesnake
