I was not able to find many photos of the International Peace Gardens online, but there were some. And some of them matched the glyphs. I figured the glyphs, along with "First West Marker" were the exact location clues.
Here is a statue of kids playing cat's cradle. I thought the glyph looked more like a coyote, but it could be a cat. Whatever it is, it is shown cradled.
They have a Matterhorn statue, and that was a very good fit for a glyph.
The Chinese garden and pagodas reminded me of these glyphs, some sort of food, maybe chinese food.
This glyph was not a very good match, but I did not know what else to match it to. There is a coarse gulch path under the footbridge.
There was one more glyph that bugged the hell out of me. Never did find a match. It was the one that sort of looked like a TV studio camera (imo). I also never figured out the significance of the number 43, which figured promenently several times on the scroll.
