SierraNevada......great link to comparison photos. They really tell the story of what it's like in early Spring. What they don't show is what happens when crossing a stream and you lose your footing, or losing your footing on a steep and icy slope.
This will be my 50th year of hiking in the Sierras and I have encountered all conditions, and cringe at the thought of people not understanding how easily it is to get into trouble.
thanks for the link.
