Half Dome Safety Analysis

Restricted permit-only access to Yosemite National Park's Half Dome summit, anticipated to improve hiker safety, did not,
Elsevier, June 26, 2019.

MAIN POINTS

2010 Half Dome Permit Restrictions
"Implementation in 2010 of permit-only access to Half Dome cable handrails along the final ascent of this iconic landmark reduced the number of people on the summit at one time, but this did not result in a significant reduction in the overall toll of associated human suffering and mortality, or search and rescue (SAR) activity and costs."

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, briefly up through the beauties of Seavy Pass before plunging down into what I call, "The Bensen Hole," only to make the precipitiously steep climb back out past the beauties of Smedberg Lake and finally over Bensen Pass, on our way back to Twin Lakes where we split off the PCT-TYT in the bottom of Matterhorn Canyon, North, to climb up through Matterhorn Canyon through Burro and Mule Passes, from the point where the PCT-TYT begin their climb East out of Matterhorn Canyon to Miller Lake, on our way back to our starting trailhead at Twin Lakes.

Check out Tim's fine description of this classic High Sierra hike, accompanied with the maps, mileages, and his excellent images of this challenging 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."
