Makes me want to go swimming...
Lol, I think it would be like swimming in toilet bowl cleaner! Get's that color from toxic mine waste.
The road to the east side of the lake is Poughkeepsie Gulch, the only sorta hard core trail in that area. One serious wall obstacle with a few different lines. Rest of it is moderate to sorta difficult. Great fun.
Every year I take my neighbors on a Jeep run. Couple weeks ago I took them over Brown's Gulch to behind the Red Mountain mining area, then over Corkscrew, Hurricane and California. These are essentially local trails for me. Been running them for 25 years and never cease to be amazed how beautiful the area is. While you're here hope you have time to do the Alpine Loop, Black Bear Pass and Imogene, too.
FWIW, these are all county roads and in no danger of being closed. A cooperative effort is underway to preserve the area exactly as it is for all interests. Sportsmen, Jeepers, 4x4s, Bikes (motor & non), hikers all have a stake and are working together to put the plan together. Much of this is private land and the big worry isn't closure, it's trophy home development. It is essentially a giant Superfund site that's never actually been declared and lots of remedial work needs to be done on old mines & tailings to stop heavy metals from reaching the creeks & rivers. Liability costs of cleanup keep property owners of these old claims from stepping forward, so the governmental agencies are trying to find a way to allow them to do remediation without risk.
