A ground and air search is underway for an experienced hiker who disappeared in a rugged area of B.C.'s Fraser Valley on Sunday.

Gordon Sagoo, 50, is an avid trail runner and became separated while hiking with a group on Baby Munday Peak, in the Cheam mountain range.

Chilliwack Search and Rescue confirmed its members are searching the area around the Chilliwack River Valley.

A fundraiser to help the SAR team with their search had raised $4,600 by Wednesday morning.
