We recently did buffalo mtn in colorado and the trail is 6.2Mile roundtrip and not the 4 shown on the website. i used a gps.
Also the talus filed is a class 2 not a class 1 as mentioned in the text.
Climbed Buffalo Mt with my son, Travis, on 28 Sep 17. Wx was marginal with lite snow cover.
I would agree with the longer distance. Unfortunately, my GPS kept breaking lock with the satellites so I cannot give you a GPS distance. For sure, 4 miles is wrong and short.
Talus climb begins as you exit the trees. There is a large cairn to mark actual trail. Unfortunately -- in limited vis -- we saw a small cairn above and to the left of the large cairn and headed up. The real trail is to the right of the large cairn. Our route was steep and difficult and marked by cairns. The actual trail is much better and carefully marked by cairns...we came down on the actual trail.
I agree with Class 2 for the talus/scree with 2.5 in some areas. With lite snow cover, I was testing hand holds and scrambling. CDH
