Nine-year-old Lana Lynn Lee vanished during a sudden flash flood on September 17, 1961, in the Wahweap Wash area east of what was then Glen Canyon City (now Big Water) in eastern Kane County, Utah. She had been playing with other children, reportedly looking for rocks and shells, when a severe rainstorm turned the normally dry wash into a fast-moving torrent. Lana became separated from the group while attempting to cross a ravine and was swept away; the other children were rescued.

Search parties conducted extensive efforts immediately after her disappearance but found no sign of the girl. Searchers believed her body was likely carried down the Wahweap Wash into the Colorado River; at that time the Glen Canyon Dam had not yet impounded the river, so the current was strong and unimpeded. Her case is classified as a lost/injured missing person case and remains unsolved.

If anyone has memories of the area, the event, or information about Lana Lynn Lee from that time, please share what is known.
