Bartlett Mountain on the original USGS map of 1970 (Copper Mountain Quad) had a measured elevation of 13,555 ft. Over the decades, the mining activity has reduced the elevation of that summit by over 150 feet. Using Google Earth, the highest elevation we could obtain was 13, 384 ft. This is obtained from a 2015 image. Roach estimated the elevation to be 13,400 ft., a figure that has "stuck" and is reflected on several sites including LoJ. While G&M included Bartlett as a ranked summit in their first edition of "Colorado's High Thirteeners," by the third edition, they had chosen to eliminate Bartlett from their list of ranked summits. Does Bartlett still qualify as a ranked summit? Our answer is yes based on GE measurements. The saddle between Bartlett and Clinton measures to be about 12,900 ft., so Bartlett technically qualifies still because it rises more than 300 feet above that saddle. But one other thing to consider, the Climax Mine is still currently in operation and so the summit elevation may be subject to further change. Lastly, we remind all peakbaggers that Bartlett Mtn. resides entirely on property owned by the Climax Mine and is therefore off-limits.
