This cache is a small Tupperware located at the summit of Whaleback Ridge.
If you plan to make this hike from hyway 22, you will need to get permission from the Rancher that is the lease holder of the land to the East of Whaleback Ridge. His contact information is available on the Alberta Land Use website In case you are unsure of the correct Lease, it is GRL33399. He is a very nice guy, so there should be no problems.
This hike took me about 4.5h from hyway 22, so plan accordingly.
