KUSA - The grandson of the man credited with founding Vail was killed in an avalanche in Eagle County Tuesday, according to the Eagle County Sheriff's Office.
Three others suffered non-life threatening injuries.
Anthony Seibert, 24, died in an avalanche triggered around 11:30 a.m. in the East Vail Chutes, a popular backcountry area between Vail Mountain and Vail Pass.
Crews were able to rescue the three other victims from off the mountain.
It's not clear if the four were skiing or snowboarding.
The avalanche danger in the area is rated as considerable. The Colorado Avalanche Information Center says slides there are becoming harder to trigger but when slides develop they are very large and dangerous.
Five people have died in avalanches in Colorado, Wyoming and Montana in the last two weeks.
Seibert is the grandson of Pete Seibert, Sr., who is widely credited along with Earl Eaton as the man who discovered the terrain that would become Vail Mountain.
The cause and manner of death will be determined after an autopsy is performed.

Chris Jarnot, SVP and COO of Vail Mountain, released the following statement:
"This is a shocking and terrible tragedy. Our hearts, thoughts and prayers go out to Tony's entire family. I want to acknowledge how integral the Seibert family is to the fabric of our community; their contributions to Vail date back to Vail founder Pete Seibert, Tony's grandfather. This is an incomprehensible loss and we will support the Seibert family and our community through this difficult time. Tony had recently starred in, "Climb to Glory," a documentary that will forever be a tribute not only to the famed 10th Mountain Division and his family's legacy but to a wonderful albeit tragically too short life."
