MONSTER SNOW PACK of the WINTER of 2019

Yosemite Announces Delayed Facility Openings

Note the Snow will Affect High Trail Access, & Damages will Affect Trails Too

Yosemite National Park Announces Late Seasonal Openings for Several Park Facilities,
Yosemite National Park, March 13, 2019.

MAIN POINTS

Damaged Facilities
“...that there will be late seasonal openings to facilities throughout the park...due to the exceptionally heavy snowpack in Yosemite National Park and the subsequent extensive damage to many park facilities.”

Stormy Winter
“...significant storm systems in January and February produced high levels of snow, which resulted in temporary road closures, rock and debris slides, and falling trees. Additionally, these storms resulted in extensive damage to facilities throughout the park. Damage to facilities includes trees falling on and damaging campground restrooms, utilities systems compromised, tent cabins damaged or destroyed, and falling trees impacting campsites, parking areas, hiking trails, and roads.”

High Sierra Backpacking Trip Report: Twin Lakes-Benson Lake Loop, July 14 to July 21, 2018

 

Trip Report
Bensen Lake Loop

July 14 – 21, 2018

Editor's Note
This trip begins and ends at the Twin Lakes Trailhead in the Toiyabe-administered Northern section of the Hoover Wilderness. It climbs precipitiously to, then over the Sierra Crest, into the heart of the very difficult backpacking terrain of the North Yosemite Backcountry.

Intercepting the routes of the unified PCT-TYT along Rancheria Creek in Kerrick Canyon, our route turns South with them, down through the beauties of Seavy Pass before plunging down into the Bensen Hole, only  to climb back out and over Bensen Pass, on our way back to Twin Lakes by splitting off the PCT-TYT to climb up through Matterhorn Canyon, on our way back to our starting trailhead at Twin Lakes.

Check out the maps, miles, and description of this fine route below...

Beetles Devastate Western Pines, Heat, Droughts, Beetles, & Fires All Continue Rising

ECO-CRASHING FOREST NEWS

Beetles Devastate Billions of Western Pine Trees

Heat, Droughts, Beetles, & Fires All Continue Rising

A tiny beetle has left Yosemite dangerously vulnerable to fire,
SF Chron, July 18, 2018.

"An epidemic of bark beetles is devastating billions of pine trees across the West in what has been described as the largest forest insect outbreak ever recorded. In California, the tree die-off is especially prevalent in the 4,500-foot to 6,000-foot elevation range of the central and southern Sierra. Yosemite Valley is just about 4,000 feet above sea level."

"Since 2010, more than 129 million drought-weakened and beetle-infested trees have died across 7.7 million acres of California forest, according to U.S. Forest Service estimates."

...there's no evidence that bark beetle infestation will subside anytime soon. In fact warming temperatures are expected to expand the insect's range, allowing it to thrive in higher elevations that previously would have been too cold for the bug to survive."
