Yukon Highway Rock Writing

As we were driving through the Yukon Territory on the ALCAN (Alaska/Canada) Highway, we noticed all this Rock Art Writing on the hillsides beside the road.  The words and sometimes symbols like a heart are written with rocks on this vast highway (actually just a 2 lane road) which stretches from Dawson City, British Columbia to the Yukon/Alaska border near Beaver Creek, Yukon .  The writers have spent quite a bit of time working on their creations out in the middle of nowhere.  It is hard to read them as you are driving past at 50 miles per hour but we took some pictures when we stopped at the Big Creek Provincial Campground in the Yukon, west of the town of Watson Lake.      

We wondered if our friends Dee and Cal wrote this.  They have 3-wheeled recumbent Trikes which they have ridden up to Alaska twice.  They advised us on our route, and we know they did go this way. 

This is Cal and Dee on their trikes. 

Here is more Rock Writing we photographed on the road beside our campground. 

Someone's initials, we guess.  You can tell this has been there awhile because there is a little tree growing up in the P. 

We think this was done by "Ailie".

This either says "YO" or maybe the "U" was lost with the shifting earth.  Who knows!
