Mount Rainier was first measured in 1924 by triangulation and this measurement was confirmed by a follow-up survey in 1956, when the volcano’s peak was confirmed by a second survey and made official. Within the intervening 100 years because the summit was first measured, know-how has developed considerably, permitting scientists to make use of GPS to extra precisely measure topography. A brand new survey is being carried out by Eric Gilbertson, a mechanical engineering professor at Seattle College.
Gilbertson, who has tackled the brand new surveying research as a private ardour mission, set a purpose in 2022 to measure the correct heights of Cascades peaks, together with Mount Rainier. An avid mountaineer, Gilbertson summited Mount Rainier in August with borrowed survey-grade GPS units from his college’s civil engineering division. His knowledge reveals that the mountain is certainly shrinking, confirming his commentary from photographs of climbers on the summit showing to be standing atop much less and fewer ice.
