As I stared at the web cams this morning, a question that's always plagued me came up again (sorry for my ramblings...)
What constitutes a peak?
Besides the absolute highest point on a mountain, what makes a summit or peak? In mountain ridge profiles you'll see multiple peaks, but obviously there's only 1 "highest elevation" peak on the ridge. For the lower peaks, what constitutes it as a new mountain peak, versus just the rocky up & down elevation on the way to the maximum summit?
Wikipedia to the rescue?
I first searched on summit & peak, which as I thought are synonymous.
As I then dug deeper I stumbled onto Topographic Prominence. From what I can understand of it, the lowest encircling topographic line (saddle point) that dictates the lowpoint before the next gain in elevation, so the distance from one peak to the next (d) needs to be greater than the distance from the lowpoint to the peak. I may be totally wrong here, but that was my understanding. With this idea a lower "bump" below a summit is not always the next mountain peak.
MWO forum readers please set me straight
So is my understanding and logic correct on this? Saddle Point (sp) to the peak (p) equals elevation gain (g) or
G1 = P1 - SP [first peak]
G2 = P2 - SP [second peak]
D = distance from G1 to G2
So then the distance to the next peak needs to be greater than g?
If D > G1 then G2 = peak?
