A man well known in Calgary's oil patch has died while skiing at Whitefish Mountain Resort in Montana.

Tom Podivinsky, 48, fell into a tree well Sunday afternoon, local media reported.

His younger brother, Ed Podivinsky, was an Olympic alpine skier. In an email to CBC News, Ed Podivinsky described him as a "wonderful father, brother, [and] friend."

"He was a rare spirit, one of the good ones. Very Sad. We feel the most sadness for his two wonderful children Ella and Gabriel and wife Mary-Beth."

Tom Podivinsky was the chief geophysicist for Calgary-based Athabasca Oil Corporation. 

"Tom was a thorough professional and was always upbeat and eager to share his knowledge with others. He will be sorely missed by his friends and colleagues," a spokeswoman from the oil company said in a statement on Monday.

Friend Mark Nichols posted his condolences to the family on Facebook. 

"The world has lost a great man, father, husband and friend to many. Life is [too] short. This could not be more the case when spoken about Tom. I have been fortunate to share many wonderful times with you. Your passing is shocking and tragic. May God bless you and all those [whose] lives have been touch[ed] by you. Rest in peace my friend."
