I removed the datum conversion since the elevation is based on the highest topo map contour. Accuracy is ±20 meters (±65.6 ft). A five foot adjustment to an elevation that is so uncertain is meaningless, IMHO. It is more important to inform the reader of the lack of precision. So 4,000+ meters is good, I think. –droll[chat] 18:48, 27 May 2011 (UTC)
Looks like you somehow mixed up Mount Humphreys with Red Slate Mountain. I agree with your reasoning, and applied your fix to that other article. —hike395 (talk) 02:15, 28 May 2011 (UTC)
