How They Just Discovered a New 14,000 Foot Mountain

Quick Overview

Researchers discovered that East Crestone, previously considered a sub-peak of Crestone Peak, is actually a new 14er because its prominence measurement of 418 feet exceeds the 300-foot threshold, leading to its official recognition as the 59th 14er in Colorado, while Crestone Peak's official height was reconfirmed at 14,295 feet.

Key Points: East Crestone Peak was newly confirmed as a 14er because its prominence was measured at 418 feet (127m), exceeding the required 300-foot threshold. Crestone Peak's official height, measured using traditional trigonometry, was historically recorded at 14,295 feet (4,357m). The official list of Colorado 14ers has increased to 59 peaks following the reclassification of East Crestone. LiDAR surveys conducted in 2018-2019 provided high-accuracy elevation data, revealing East Crestone's prominence to be 418 feet relative to Crestone Peak. The video explains that measuring height above sea level (like Everest) differs from measuring prominence (how much a peak stands out from its saddle point). Modern measurement techniques like GPS/GNSS and LiDAR offer far greater precision than older methods like triangulation or spirit leveling.

Context: This video details the process by which researchers, specifically Eric Gilbertson and his colleagues, investigated the status of East Crestone relative to Crestone Peak in Colorado. The context revolves around the definition of a '14er' (a peak over 14,000 feet in elevation) and the geological concept of prominence, which determines if a secondary peak qualifies as a separate 14er or remains a sub-peak.

Detailed Analysis

The video explains how East Crestone, previously thought to be a sub-peak of Crestone Peak, was officially determined to be a new Colorado 14er. The traditional survey of Crestone Peak in 1967 yielded an elevation of 14,294ft, but East Crestone was only estimated at 14,280ft. Modern surveys using GPS and LiDAR provided crucial data. Specifically, LiDAR data processed manually showed Crestone Peak's highest point at 14,302.1ft and East Crestone at 14,297.9ft. Crucially, the prominence (height above the lowest contour connecting it to a higher peak) of East Crestone was found to be 418 feet (127m), significantly surpassing the 300-foot threshold required for a peak to be officially counted as a 14er. This confirmed East Crestone as the 59th 14er. The video also contrasts absolute elevation (like Everest, 29,032 ft above sea level) with relative height from the Earth's core (where Chimborazo is tallest due to the equatorial bulge) and height from base to peak (where Mauna Kea is tallest).
