Young America Lake is hidden in the
Sierra Buttes massif.
Located north of the craggy peaks of Sierra Buttes,
Young America Lake's outlet is Sardine Creek.
Its water flows through the Sardine Lakes
and continues downstream toward the
North Fork of Yuba River.
To get a bird's-eye view of the greenish blue
glacial lake, hike along
Sierra Buttes Lookout Trail
and peek through the conifers
while you are approaching the rock buttresses of Sierra Buttes.
The picture above shows snow and ice that remained until July 2017
from the precipitations during the winter and spring of 2017.
The lake is named after (I assume) the historic
Young America Mine.
Virginia Lutes recently put together the numerous stories
about how the Young America claim came into being:
