Failed attempt to reach Lyons Lake (Desolation WIlderness)

The plan was a nice, gentle cruise up the Lyons Creek Trail to camp at Lyons Lake. Start around 7000' and hike up to about 8400', more or less following a creek and/or drainage basin... piece of cake, right? Right, except that early May in the Sierra is still capable of dishing full-on winter.

Long story short, popcorn sized hail started to fall at the exact moment that we pulled into the trailhead parking lot.

All of 100 meters up the trail I was already stopping to oggle the surprise contrast:

We danced over streaks of snowpack for about a mile.

Observe, winter wonderland:
