FIGURE 3-1 Columbine at 12,400 feet, the upper and middle Blue Lakes, and Dallas Peak, Mt. Sneffels Wilderness, San Juan Mountains, Colorado. I discovered this group of columbines while scouting on the second day of a six-day backpacking trip to the Blue Lakes region and shot it two days later. This was my third backpacking trip to the Blue Lakes area in the previous eight years. Canon EOS 5D Mark IV, Canon EF 16-35mm f/2.8L III USM at 20mm, ¼, f/22, ISO 800.
