Were you referring to the Stoney Creek area?

If RCMP has reason to believe she was traveling on foot and was last seen at Stoney Creek area, and the search should be rather straightforward. From the map, it is not a deep forest and even she stayed off trail and got lost, she should have been able to get out of there and ask for help in the residential area nearby. Unless she fell sick, unconscious and/or injured and was not able to call for help. Hopefully this morning’s search party has already found her safe and sound. If not, she might have continued on foot up north towards SFU area, or she might have travel south to Burnaby Lake (less likely though). Then you may want to consider organizing a bigger search party for that. RCMPs are professionals, but don’t solely rely on their resources. Time is the essence. Please keep us posted if/when you can. Fingers crossed.
