I've been waiting for a website like yours. In late August or September, 1973 my husband and I climbed Mt St Helen's, before it blew. We met 4 young people near the top and shared our camp spot with them. The next day my husband took a picture of the four of them on the way to the top.
It's a gorgeous picture and we've often been sorry that we didn't exchange contact info with them so they could have a copy. That was before the days of internet.....now with a website like yours, possibly someone would recognize them!
