= DGVV Couloir = The DGVV Couloir, or Demetri-Gauthier-Victor-Victor Couloir, is a north-east facing ski couloir on Bear Creek Spire mountain in the Sierra Nevada in Inyo County, California. It is named after the 4 skiers who first ascended and skied it downhill on April 26th, 2024

History of first Winter Ascent and ski Descent
Bear Creek Spire mountain, over the Rock Creek canyon, is a well-known place for summer climbing since it has been cartographied in 1908 by Joseph LeConte, James Hutchinson and Duncan McDuffie. Its north face is a common pass for hikers (in summer) and skiers (in winter) who want to reach Mount Gabb further west.

Despite the extensive presence of Bear Creek Spire mountain in specialized literature, the north east facing ski couloir is not mentioned in what is considered as the reference guidebook for backcountry ski in the Rock Creek valley. On the morning of April 24th, 2024, a group of 8 backcountry skiers, led by 2 experienced alpine guides, Demetri Zouboukos and Miles Britton started skinning in the Rock Creek canyon, with objective to be the first team to ascent and ski down the north east facing couloir of Bear Creek Spire mountain. They established camp in the inner Rock Creek canyon region, just east of Treasure Lakes, about 3000 feet shy of the top of Bear Creek Spire mountain. After spending April 25th, 2024 acclimating to the altitude, the skiers packed their gear and started approaching the north-east facing couloir on April 26th, 2024. Around 10am they reached the bottom of the north east facing couloir, and the team had to make the difficult decision to split in two to only leave 4 skiers attempting the ascent. Indeed, a thunderstorm had started the previous night and had made the snowpack to weak to handle as much as 8 skiers on the way down. The 4 most confident skiers from the team, Demetri, Gauthier, Victor and Victor were unanimously chosen by the group to be the ones to bootpack, while the 4 others would stay at the bottom of the couloir as support incase of an emergency. Around 10:45am, Demetri, Gauthier, Victor and Victor reached the top of the couloir, could safely ski it down and regroup the rest of the team who stayed downhill.

It was then decided to name this couloir the DGVV couloir, in honor of the 4 members of the expedition, Demetri, Gauthier, Victor and Victor who skied it, in that order.

Topographical features
Given the extreme weather conditions, it was almost impossible for the expedition members to make any extensive topological measures. The 4 skiers who made the ascent though agreed that the maximum steepness of the slope should lie around 45 degrees.
