November 20, 1936: "I cannot say that I envy the Strawberry Peak Lookout who has to meet a total of 5743 visitors during a season, but now, just for comparison, let's shift to another Lookout in the northern part of California, on the Trinity National Forest. Black Rock Lookout at an elevation of 7769 feet, located on the Yolla Bolly district of the Trinity; received between June 22 and October 20, 1936, a total of 25 visitors. On the total, 14 were Forest Service employees such as packers, relief lookouts, and forest officers; five were cattlemen and 6 were hunters. The longest period between visitors dated from August 24 to September 14 a total of 21 days. If anyone thinks that three weeks is only a short period, they should try spending it on a lookout peak with only a telephone for company." (California Ranger)
