If All Goes Well, There Will Be No Swimming

February 06, 2016 Posted by: CJ - Creative Media Assistant (Yosemite Valley)

Like in summer, there are bodies of water to cross when travelling in the wintry Yosemite Wilderness. But winter has that extra bag of tricks: it’s cold. For some, the coldness itself may not be much of an obstacle to overcome, but winter changes to a landscape can test anyone’s abilities and common sense.

Wildfire: friend or foe?  Within the Sierra Nevada, fire has been an integral part of the ecosystem for thousands of years.  During that time the flora and fauna have adapted to a Mediterranean style climate of hot and dry summers allowing for a vastness of fire tolerant plants to adapt to that natural cycle.  A unique plant that has a rich and distinctive life cycle within this unique ecosystem is buckbrush Ceanothus.
