From Denver it takes ~3 hrs without jam to get to Keystone which had a base elevation of 2830m already. The highest town/resort I have been so far.
I was here for a 5d4n conference,
the 1st day it was already snowing and everywhere was covered with snow and looked grey
The snow was really deep, if it wasn't for the clearing of the snow on the roads, it would be so hard to walk on them. Your leg can just sink in them and it's hard to pull yourself up.
