Irene B. Herding, age 75, disappeared after leaving her home near Darrington, Washington, around July 20, 1990. An experienced hiker, she did not tell anyone where she planned to go. On July 26 her 1977 Chrysler station wagon was found parked in the Darrington area. A closer check on August 23 showed her purse and camping equipment still inside the car, suggesting she was not prepared for a long absence.

A search and rescue operation followed, with teams combing the surrounding forests and mountains, but no trace of Irene was ever located — no clothing, gear, or evidence indicating her route or what happened.

If anyone knew Irene, her usual routes, or was in the Darrington area in July 1990, can you share information that might help explain what happened?
