I posted a link from that page to here. People on the Facebook page are discussing some of the same things. There's a search this Saturday. The exact place will be announced tomorrow night because the page admin is following up leads to get more information.

If anybody can photograph the north face of Fuller Ridge in full daylight with a good camera and zoomed in, an image-editing program might find pixels that have more blue in them. David's blue backpack might be enough to alter the numbers in a pixel, even though we might not see it by looking at the photos.

Wow, that sounds like a great idea, Perry.

This afternoon I went a little ways up the PCT and took some photos of Fuller Ridge from a couple places. Couldn't get an early start because I barely recovered from being sick, so the lighting is not the best, but the photos still show some things. Also couldn't find my small tripod, so I had to stabilize the camera by resting it on boulders.

The numbers in between can be typed. To download as TIFF's (big files), change extensions to .TIF

I tried the method that I mentioned, but there's too much digital noise, and the white balance is off on some. It might work with full daylight and a better camera shooting in raw mode.

A telescope in full daylight could be used to search bare areas. Going higher up the PCT would likely give a better view of the treeless area on the left that is partially obscured by the large rock face (images 870, 871, 884, 885, 886). The areas with a lot of trees can really only be searched by being there. And with so many trees near the top, it seems unlikely that a person could slide a long ways, although it looks like there may have been a couple of narrow snow chutes to the right of that treeless area.

Hey, intriguing! Can you post the locations you took pictures from? What were the specs on your camera? I have a beefy DSLR ( 36.3 MP full-frame ) and a 500mm telephoto lens. If I can find time ( a 5 hr drive for me ) I can have a go at this too. I'll definitely shoot in raw.

What would be really interesting is to do too is a control test with a piece of colored fabric and see how it shows up in pictures.

I always have more ideas than time ...

Turns out it was about 2 weeks before the last sighting of the missing hiker, close enough in time for conditions to still be similar in the area:
The hikers blog: http://theramblingnews.blogspot.com/2017/04/rattlesnakes-to-blizzards.html
The hiker warning others on a PCT forum: https://www.whiteblaze.net/forum/showthread.php/124075-Fuller-Ridge-Mile-178-190


It sounds like Dick fell near Strawberry Cienega:

He estimated that he slid 1,000 feet and that he could have slid further if he hadn't ended up in some rocks.

I think another hiker slipped after leaving Tahquitz Peak. At the moment I don't have the link.

Just saw your reply. That's a good idea to test the theory. Here are the 2 locations I took photos from:
http://mapper.acme.com/?ll=33.87212,-11 ... 0Peak%20CA
The first set of photos were from the higher location, 2nd set lower down. The camera I was using is an old camera with I think 2 Megapixels but a very deep optical zoom. Most likely 8 bits/channel and more noise than newer sensors.
