Obsidian Boulder is an amazing boulder with one pure line on it. This requires a tough, little hike, but it is well worth it. This talus is loaded with potential, too.

There isn't really any super easy way to get there, but it isn't horrible compared to longer alpine approaches like Lincoln Lake or Upper Chaos. Hike the left side of the large talus from the treeline area. It's not particularly easy, but it is well worth it.
