It looks like the temp trends have turned the corner. However, when I climbed at Lumpy recently when the forecast was 50s and low winds, the wind was blasting driving the wind chill into wintry conditions higher on the formations. It was still a great day but I was glad I had layers and a soft shell jacket and pants.
Check Google Earth...it looks like there is a washout starting high on the left side of Sundance from the flood. I can't tell if it is in into the descent.
