Went up on a Mother's Day hike to the Crystal Mill taking the low road in. I let the ladies return the same way, but I completed the Lead King Loop which goes up this road. Above 10,500ft things were still pretty snow-covered. Not impossible without, but wished I had brought my snowshoes. Feet got really wet, glad I brought extra pairs of socks.

The road was completely obscured by snow near the top, so I got a little lost and followed the Silver Creek watershed too far up, had to backtrack. Wasn't too hard.

Many creek crossings, maybe 6-7. I did see fresh bear tracks in the snow and mud about 1.5 miles up into Lead King Basin from the town of Crystal.

All in all, a beautiful hike despite the challenges and discomforts of the early springtime.
