I sure have lots of undated prints. My lab at this time printed LOTS of numbers on the back, but no dates. Dates would have been nice. (I can guess what year it was based on the address I used on the order envelope, in this particular case.)
I hope I have scans of these somewhere. (Perhaps this stack of unlabeled CDs? Gah!) These are images from Desolation Wilderness, up near Lake Tahoe, here in California. It is a relentlessly gorgeous, high elevation, roadless wilderness with stunning lakes, snow still piled on the peaks in summer, and (at that time) a remarkable number of mosquitos.
Yes, I am the kind of gal who hauls an antique twin lens reflex camera and medium format film into the high Sierras. But you knew that.
