Keith Patrick Zimmerman, 22, disappeared from Kenai Lake near Seward, Alaska after setting out on a canoe trip with a friend, Richard Erchinger, on June 26, 1977. Both men failed to return and were reported missing; neither was seen again and no canoe, personal effects, or eyewitness account has been located.

Authorities presume both men encountered trouble on the water and likely drowned, but the exact circumstances remain unknown. The lake’s size and the rugged surrounding terrain complicated search efforts, and the Alaska State Troopers kept the investigation open.

Does anyone have memories of Kenai Lake that summer of 1977 or information about Zimmerman or Erchinger’s plans that day?
