Parks Canada spokesman Steve Holeczi (hole-EIGHT-zee) says rescuers received a distress signal from the Wapta ice field, a popular area for skiers.
Poor weather and a high avalanche risk in the mountainous area hampered search efforts and rescue crews couldn't get close to the area until Friday.
Holeczi says a helicopter spotted two people on Friday who were waving and rescued them.
He says the pair had dug a snow hole and were well equipped with sleeping bags and other outdoor equipment.
But Holeczi says there was no sign of a third person.
He says all three skiers are from British Columbia.
Poor weather hampered efforts Saturday and rescuers are hoping for a break in a weather in hopes of finding him.
