Yosemite National Park
Past Fire Activity

In Yosemite, fire records date back to 1930; therefore, Yosemite fire managers have 80 years of records on fire and suppression activities. Tree ring studies provide fire frequency dating back hundreds and thousands of years. This historical information has helped shape goals and objectives for today's fire management program. Scroll down to view a graphic representation of fire activity from 2000-2010. Also, find annual summaries of the 2010, 2009 and 2008 fire seasons. (Compare to this year's current fire activity.)

Nevada and Vernal Falls

Did You Know?
In Yosemite Valley, dropping over 594-foot Nevada Fall and then 317-foot Vernal Fall, the Merced River creates what is known as the “Giant Staircase.” Such exemplary stair-step river morphology is characterized by a large variability in river movement and flow, from quiet pools to the dramatic drops of the waterfalls themselves.
