Hi Steve,
"You da Man". Magnificent hike! I too want to hear all about it. Why down to Iceberg lake, and then up the chute?
Dropping down from Whitney-Russel col to Iceberg was easier for me than trying to traverse across to join the MR at a higher level . Let's see what Steve says. .........plus it is last chance for a fill up.
As for the other topic, I don' think everyone reaizes that the faint change in shading that Wagga is talking about is a STRAIGHT line,and when it does change it is angular, not like a contour line
