On Friday, April 28, 2017, around 1 pm, the Big Trees Lodge manager contacted Yosemite National Park regarding two of her employees who were late for their morning shift, and who hadn't been seen by co-workers in about 24 hours. Initial investigation revealed they were planning on climbing Wawona Dome. A search was initiated but the employees returned on their own later that evening after having spent an unplanned and very cold night on the Dome.
On the afternoon of April 29, a 39-year-old hiker above Columbia Rock on the Yosemite Falls Trail left the trail and attempted a short rock scramble. When sliding down the rock, he broke his ankle and found himself stranded and struggling to maintain consciousness due to his severe pain.

At 8 am on December 28, 2016, two trail runners—James and Christine (not their real names)—started up the John Muir Trail from Happy Isles. They didn’t have a particular goal, route, or schedule in mind, but they did have small packs with headlamps and light jackets. Both were experienced with mountaineering, ice climbing, and backcountry snow sports.

The current Sierra snowpack melt is a welcome occurrence for Californians and its visitors and Yosemite National Park is now reaping the water runoff benefits. The Merced River is active with visitors floating through the Valley. Unfortunately, increased activity, along with lack of planning, preparedness, and inadequate equipment has led to three search and rescue cases involving four persons just in the past week.

On Monday, June 6, 2016, Yosemite Search and Rescue received a report about a hiking group possibly stranded without water or having trouble with a water crossing.

The Nose is considered to be the easiest full-length route on El Capitan, which makes it extremely popular and draws relatively inexperienced big-wall climbers. But the Nose also is a complex climb, requiring a large repertoire of techniques that may be unfamiliar to newcomers.

On Monday, November 2, 2015, winter arrived in Yosemite. By early afternoon, rangers began enforcing tire chain requirements, and the snow plow drivers began their first operation of the winter. White stuff dusted the Badger Pass chairlifts and rain soaked Yosemite Valley. Visitors and park staff alike bundled in jackets, drove more slowly, and marveled that water was finally falling from the sky. It’s worth noting, however, that not all park visitors found Yosemite’s first 2015 winter storm to be so beautiful.

Three hikers were injured along the Merced River in the first six days of September. In each of these incidents, individuals made what seemed like reasonable choices to engage in activities along a seemingly benign section of a river but the injuries that resulted were painful ways to end a vacation, and sadly, one which was life altering.

On Monday, June 29, a 27-year-old male got himself into quite a cliff-hanger, literally. In Yosemite Search and Rescue language, we simply call this becoming “ledged-out.” While this might seem unrealistic on a simple hike, it is a very real possibility at Yosemite National Park.

With the unseasonably warm, sunny weather this spring, the number of hikers has risen dramatically over the past several weekends. Trails out of the Valley are open for a long way, with little snowpack, leading some adventurers to travel farther than they might normally at this time of year. We have had an unusually high number of search and rescue missions, all stemming from one common cause: leaving the trail. Here are the stories from this March in Yosemite.

Upon reaching the point, overwhelmed with the spectacular view, he decided to attempt to access another spire just a little farther out. This effort required some scrambling, and he ultimately fell down the slope, sustaining a broken arm and several more minor injuries.

Key components for making any given hiking adventure safe and successful are (1) having an adequate fitness level for the chosen hike and (2) knowing the limits of your own physical abilities.

Moments later, two more 17-year-old males, unrelated to the previous group, walked into the clinic and, similarly, requested medical attention for lower extremity traumatic injuries caused by sliding down the Silver Apron.

Two hikers slipped and then fell vertically onto large uneven rocks near Chilnualna Falls. Scrambling off-trail is one of the leading causes of serious injury and death in Yosemite.

Although the way down after a technical climb may involve relatively easy scrambling or hiking, a hiking trail can be as treacherous as the climbing route itself, should the climber’s attention stray. Whether a climber or a hiker, be sure to focus on what you’re doing on the way up, as well as on the way down (especially if you’re off trail).
