The First 100th Peak, June 1946. One of the most famous photographs in the Hundred Peaks Section's archives shows Jack Bascom congratulating Weldon Heald on becoming the first person to ascend one hundred Southern California mountain summits of more than 5000' elevation.

"Sam" Fink. -Photo by Weldon Heald, Angeles Chapter archives.

The great event occurred on Grouse Mountain. Of this first 100 Peaks celebration, Jack Bascom recalls: "It was a beautiful June day when Weldon Heald and I hiked to Grouse Mtn. He was excited over the prospects of finishing his 100 Peaks. Although I had been with him in climbing a dozen other peaks on his list, I hadn't as yet become afflicted with the 100 Peaks 'bug.' In 1946 there was no paved road to Mt. Pinos from Cuddy Valley and it was necessary to go on a one-way road from Lockwood Valley. We left the car at the highest point on the road and in less than an hour of cross-country travel reached the top of Mt. Pinos. From there, we followed the present trail over Sawmill to Grouse. We had no champagne (its use in HPS celebrations hadn't been discovered), and to record my congratulations, Weldon set up his camera for a picture. I remember his enthusiasm and excitement, while my thoughts were, 'Poor fellow, he must think that someday others will be doing this'. I always enjoyed my trips with Weldon, for besides his fine personality, he was one with many new ideas and he had an abundance of mountain knowledge."

Grouse Mountain and Sawmill Mountain are in the Chumash Wilderness. Permits are not required.
