May 28, 1970: " The message went out load and clear for all to hear. "Are there any bears on Lemmon Rock?' Larry Davis, manning the Forest Service lookout tower there, radioed to his counterpart Wilma Lewman at the Mount Bigelow lookout eight air miles away. Miss Lewman who has spent much of her life in the woods, radioed back to Davis, who is just starting his first season as a lookout: Yes, there are bears in the area. 'Well I was trapped for 20 minutes in the outhouse by one just now.' Pause. 'What?' Message repeated. Forest Service officers said the message probably was heard by 50 or 75 persons over the agency's powerful radio network." (Tucson Daily Citizen)

June 12, 2015: Coronado Forest officials announced that the lookout is closed to visitors. The reason stated, visitors in, on and near the lookout poses a distraction to the staff, and it is far more important to be vigilant for fires than to entertain the public. Hiking the trail is still open but the lookout structure is forbidden.
