The Sierras are amazing. At one point on the PCT Idid not go below 10,000 feet for about seventy miles. It seams like every day we climb a pass. Then we follow a steam down to a fork and climb a stream to the next pass. After Muir Pass we got about Four hours of frozen stuff coming out of the sky. It was unpleasant but we made good miles.
There is still some snow in the passes. It can be hard to find the trail because of the snow. The snow can be scarry. At times a fall would be dangerous but hopefully not fatal. The snow can also be fun. I slid down Mule pass yesterday on my but. The hikers at the bottom said it was too early to have that much fun. They were wrong.
