Take a moment to lose yourself in the roar of Vernal Fall, recorded this week as melting snow and recent rains brought it back from a summer low. If you plan to hike the Mist Trail corridor this winter, be prepared for snowy and icy conditions!

It is possible to drive from the town of Sonora to Yosemite via Highways 49 and 120. (Sonora Pass is closed, though.)

That is true... they have big years every few years. The reason isn't well understood.

Rap-tap-tap-tap-tap! Bears and squirrels aren't the only wildlife happy about the abundant acorn crop this year...acorn woodpeckers are busy stocking their "granary trees" with thousands of acorns for the coming winter. Family groups use the same granary trees for generations.

This is from Virginia Peak, NV, not Virginia Peak, CA (which is inside Yosemite).

Good morning! The Four Mile Trail is closed below Union Point (about halfway up the trail) due to snow and ice.

Probably not - snow at that elevation has been melting steadily over the past week.

The first snows melt away to reveal a carpet of acorns the colors of sunset. Their abundance begs a question: can each one possibly contain a mighty oak?

Mountain yellow-legged frogs may have once been the most abundant vertebrate in the Sierra Nevada; today they are endangered and rare. Check out the newest episode of Yosemite Nature Notes to find out why, and what gives frog-lovers hope for their future:

Color Challenge! It's winter and while landscapes tend towards grey, brown, and white, we challenge you to find some bits of color during your next Yosemite visit. If you've visited during winter and seen various shades of the rainbow, what colors do you remember seeing?

What is a "snow cornice"? When prevailing winds blow snow over sharp ridges, it builds out sideways over time like a overhanging ledge, threatening unwary mountaineers. Photo from the Yosemite Archives, looking down towards a snow-covered Ostrander Lake.

The Big Oak Flat area is just inside the entrance to the park on Big Oak Flat Rd. (Highway 120).

Yosemite recently hosted a training for structural firefighters from across the NPS. Firefighters practiced fighting vehicle fires, search and rescue, hose deployment, and other critical skills. We are grateful for their dedication and willingness to protect our national parks.

Yosemite Valley received its first significant snowfall today (several inches!). Some people think days like today are the best days to be in Yosemite. What kinds of days are your favorite in Yosemite?
