From the Inyo Sheriff Facebook page:

"Inyo County Sheriff's Search & Rescue is testing a PSAR program on the Whitney Trail. PSAR includes active interaction with trail hikers (boots on the ground), passive informational (trailhead signage), cooperative support (local businesses catering to the hiking public: motels and retail outlets) and social media (this posting).
The PSAR program includes: emergency contact information and medical issues, trail conditions, weather conditions and team issues.
The most recent "boots on the ground" activity was Sept 9-10 from the Whitney Portal to Outpost Camp. A total of 19 groups were contacted with 61 hiking members. If you were part of the hikers contacted, we would appreciate your comments. Please send to: Inyo SAR, PO Box 982, Bishop, Ca. 93515.
The topics with the most discussion:
1 - reliance on "good weather" reports with bad weather the night before and on the current horizon.
2 - camp at Outpost Camp and start the longer summit bid from there or risk possible bad weather conditions overnight at Trail Camp and start the shorter summit bid from there.
3- not starting the summit bid early enough to get off the summit and Trail Crest before bad weather moves in.
Large groups with different physical capabilities and overnight equipment complicated this decision process.

Inyo County Search & Rescue: We are a dedicated group of volunteers called upon to provide search and rescue services to all reaches of Inyo County, CA. As an independent non-profit 501c3 organization, we partner with the Inyo County Sheriff's Office to better provide services.

What is a PSAR program? Answer from Yosemite:

Parabolic Stop and And Reversal?

Interesting that the top 3 subjects were all weather-related. If you look at actual SAR activity on Whitney in recent years, you might get the impression that the top 3 subjects would be AMS, navigation off the summit, and descent late in the day, especially above Mirror Lake,

Apparently, the topics most discussed with hikers on Sept 9-10 were the three listed, not recent SAR activity. SAR is looking for feed-back from the persons involved in those discussions. Were you involved in the discussions? Perhaps you should contact Inyo SAR with your questions. Although I am former SAR member, I do not represent them, and was not part of those discussions.

Yes, that's what I understood. Just wondering why those were the top 3 discussion topics.

Thanks to the Forest Service and Ranger District for their support.
A PSAR volunteer totaled 9 Whitney trail days so far this season.

Hi Jed,

You probably didn't intend to start a parallel thread. It's an interesting topic. Please join the conversation at:

I merged the two threads, added Ed's image of the leaflet.

Great weather for a 9/14/2017 day hike to Trail Camp. Encountered 5-6 JMT groups on the finish hike to the Portal. No doubt very disappointed about the kitchen closure. All were pretty much hammered by the weather conditions over the past few days and happy to see the sunny day finish. One bivouacked on the summit and considered hiking out at 1am during a hard cold blow: common sense prevailed.
Heard a few accounts of someone staggering around Outpost Camp with AMS or worse: looking for the summit trail, wondering if this was Trailside Meadow, ascending out of Outpost and then descending. It's amazing how a group will let that happen. Another account from at least 4 groups that saw a father and fatigued son at Lone Pine Lk junction, Outpost Camp and Trail Camp. A few suggested that they should consider descending. I never caught up with them to see for myself. Hope they made it down okay.
Lots of mosquitoes in the sunny afternoon below the Lone Pine Lake trail junction and the deer migration to lower elevation may be starting.
