Thank you Steve.
I called both numbers. The 6200 is just a recorded facility information. However, on the 6222 I could at least deposit my information. I was a bit puzzled that they have no direct email so I had to spell out virtually all information including words like Canon, foto and Switzerland. I hope the friendly and helpful lady got it right. She also gave me an additional number 1-760 937 2257 which she said was at Whitney Portal. There was no answer though. I'll keep trying. Mountain Radio at Bend, OR was kind enough to air the request trying to locate the guys who wheeled us down to Lone Pine. No reaction as by now unfortunatly.
