slingblade: I hit the JACKPOT, one of the best videos I have found of the hike/hunt off the Durango Silverton RR in Unit 75, the 36 mile hike from Elk Park to Chicago Basin and then Needleton for train pickup again. Notice the mtn goats.
This will show you the terrain and what 74,75 and 751 is all about, of course not this rugged in all units. This hike was in Unit 75 perhaps Unit 751 also, when near Vallectio Creek.
I could not do it on the PM, 24hour web site kept loosing my connection...Grrr !
