There are some threads about this on WB, including a post from Squeaky:
"..........came onto 'Fuller Ridge' which would have been fine if it had of stayed on the western side of the mountain, but 'Fuller Ridge' was just caked in snow on the Northeast side and decided for some reason to follow the footprints that went straight down and got down a couple of hundred feet no change in the montain it went straight down, so I looked at the maps again , again no visual reference because of poor visability, looked at maps and saw I was heading down North face of 'San Jacinto' so decided to turn straight around headed back up and studied maps some more and decided if I was on 'Fuller Ridge' to follow the ridge line as far as possibe and lucky enough someone else had been in that direction which was helpful in a lot of areas cause I didn't have any crampons, kept checking the baring off the footprints and kept heading Northwesterly, sure enough came to fire service road and met up with the couple whose footprints I had been following and shook their hands and thanked them pretty much for getting me through 'Fuller Ridge'.............
this is part of my journal entry for the 9th of may 2005. those footprints went straight down. its around the time when Donovan went missing. i have the worst feeling thinking they could be Donovans. they only went down. and they were not fresh enough to be made on the 9th, but no older than a few days.
visibility was very poor but i am sure the footprints went down from the start of fuller ridge"
