I broke down and went bottom to top on Saturday. Wow, do I need the Altitude.
I counted over 100 total steps in snow. Almost all are not in any kind of 'deep' snow, but you are generally at the top of a sheet of snow you would NOT want to fall/slide down, and the 'Path' over the top of these sheets of snow is generally not more than 8-12inches wide. I did not look down, and made every effort to put my feet exactly where they should go.
I went through in the 9-10am range, finishing about 9:45am, and jumped on the 1st Train down. At that time, the paths were stable, but already slightly slushy. Air Temp at the top was only 31-32, but the Sun on Saturday made it feel SO much warmer, I had no need for the jacket or gloves.
The first Snow-Free day on Barr Trail in 2009 was July 19th...
http://skyrunner.com/snowpeak.htmBarr Trail Mtn Race is next Sunday, so go Saturday or go SUPER Early Sunday if you want to start at the bottom and see if there's Snow at the Top.
Happy Training!
