No caption or date, but it looks like the Grand Canyon (or Mars surface, but more probably the former).
No caption or date, but I'm guessing sisters in spring formal dress circa the 1940s.
No caption or date, but I know for certain that it's a yucca brevifolia, probably taken locally since that is what everything looks like out here.
These three are my favorite of the bunch. They are all labeled "Jim's 8th grade play. June 1928."
