April 7, 1933: "We stopped to see Demar Colegrove as I wished to talk to him about putting a lookout on that high point, but he had gone to Crescent City and would not be back for a day or two." (P.S. King Field Report)

April 26, 1934: "Mr. Ostrander and Mr. McCarty went up and looked at the lookout on Mr. Colegrove's land and they were not very well pleased with it, as they made no tower but set the house tight on top of the mountain and the vision to the north is obstructed about fifty per cent. I met Mr. Mitchell in Gold Beach and told him I thought it advisable not to fall the timber, but to go up one of the big trees there and cut a couple of trees and make a triangular tower, using one standing tree. This would give them a clear vision of the entire country and unless they fall about three acres of timber the lookout would be of no value to the Forest Service. Mr. Colegrove does not wish the timber felled. Mr. Mitchell will look into the matter on his return." (P.S. KingField Report)
June 12, 1934: "Met Mr. McCarty and Mr. Ostrander and the next day we drove to the Colegrove Lookout. They have built a good standard lookout house and have felled the timber on the north side which gives it good visibility for the entire country. The telephone line is not in yet but Mr. Mitchell informed Mr. McCarty that he would have it in a few days. The telephone service from Brushy Bald is not very satisfactory and Mr. Ostrander is a little lax on inspection and I instructed him and Mr. McCarty to do over all operations in that district and see that they all comply with the law." (P.S. King Field Report)
June 14, 1934: "Several new lookout cabins have been erected in the county during the past year. One has been built on Colegrove Butte, near the Oregon Coast Highway, about 25 miles south of here. It is reported that Stanley Colegrove will be the first observer to occupy this post. The Colegrove station is said to be the closest of any in the state to a trunk line highway, being only a quarter of a mile back from the road between here and Brookings." (Curry County Reporter)
