The Nine Corner Lake boulders are a nice collection of glacial erratics in the Adirondacks in upstate NY. The boulder field as a whole is a large, but easy to navigate area. There is a good concentration of boulder problems here of all difficulty levels (from V0 to V12) with many open projects. This guide details over 320 problems, with many classics, including: Chillen (V4), The Origin (V5), Into Thin Air (V6), Frog Legs (V7), Thorazine (V8), Instant Yoga (V9), Rise of Nick Stoner (V10), and Overburdened (V11).
