Looking at maps on line you will see that they show that there should be a road here called "Queen Road". There may have been one at one time however there is no longer a road. The road may have been around before the nearby highway was built and I am sure at that time lots of roads changed. We were riding around the area and thought this would be a good place for a cache.
As always bonus points if you know who "Mark Chisholm" is.
