The River Changelings: Monitoring of Benthic Macroinvertebrates in the Tuolumne River

September 20, 2014 Posted by: AH - Park Ranger (White Wolf)

On June 6, 2014, a small group of Yosemite Ranger Naturalists set out to find some elusive creatures…with nets and water shoes.

 

Sculpture? Jewelry? Pegmatite?

September 07, 2013 Posted by: JL - Park Ranger (White Wolf)

Sometimes the planet Earth seems like an inventor constantly coming up with new ideas. On a walk near White Wolf earlier this season, I was surprised to find a jammed-together patch of milk-white rocks almost two feet long; geologists call this pegmatite.

 

Pacific Tree Frog: Pseudacris rigilla

September 07, 2013 Posted by: CF - Park Ranger (Yosemite Valley)

Yosemite is home to many things. Our most recognizable features are towering granite walls and waterfalls, but if you take a closer look you just might be lucky enough to see some of the tiny creatures that dwell in and around them. One such creature is the Pacific tree frog.

 

Rainbow Walk to Lukens Lake

July 06, 2013 Posted by: AH - Park Ranger (White Wolf)

A walk to Lukens Lake from White Wolf these days presents you with a panorama of colors that only deepen with your continued observation. Don’t be distracted by the meadows bubbling with Jeffrey’s Shooting Stars leaning and bending in every direction or the towering Mountain Bluebells overtaking certain sections of the trail. Take a closer look on your hands and knees at the 4 different species (and colors) of little violets blooming or the herds of pink elephants (Elephant’s Head) gathering higher up above the ground in a few special places. Don’t miss the Green Rein Orchids as you bound along the trail towards the glowing Sierra Butterweed.

 

Orange Peels in the Forest?

June 10, 2013 Posted by: EH - Park Ranger (Yosemite Valley)

Hiking along a trail in the White Wolf area, to my surprise I saw an orange peel on the forest floor! Did someone litter? No, it wasn’t the discarded shell from a delicious fruit we know well, but a cup-shaped fungus growing upward from the ground.

 

Did You Know?

Yosemite Museum

When it opened to the public on May 29, 1926, the Yosemite Museum became the first museum building in the national park system, and its educational objectives served as a model for parks nationwide. It still functions much as it was originally intended, and currently exhibits items which mainly reflect the Native occupation of Yosemite Valley and its surroundings. When in the park, you can visit with one of three cultural demonstrators who primarily staff the Museum.
