This series was originally planted by Der Mad Stamper, but he seems to be missing in action and I finally took it upon myself to replace the two missing missing boxes in his [http://web.archive.org/web/20130618024015/
http://www.mitchklink.com/letterboxing/clues/crgfalls.htm Columbia River Scenic Highway Falls] series. However, the original hiding places are no longer usable so the clues need updating. Use the clues below to find the replacement boxes.
As for the stamps I carved, since Der Mad Stamper was kind enough to post images of the stamps on his webpage, I was able to recreate the original images. And since I had found the three other letterboxes that weren't missing, I even knew the correct sizes the replacements should be (assuming they were all the same size, which could be an incorrect assumption, but probably isn't).
This series has absolutely beautiful stamps, and I couldn't let another day go by without the missing boxes being replaced. Enjoy the hunt and these beautiful stamps!
Clue
Ponytail Falls: Follow the original clues up to the foot of the large pine tree. The original location for the box (as best as I can figure) isn't a very secure place, so I moved it slightly about ten or fifteen feet away from the tree. Follow the trail leading away from the tree that ends after about ten feet. To your left should be a decent sized boulder with a fern growing on the right side of it. Look behind/under the fern for a smaller rock resting against the larger boulder. The letterbox is under that rock.
Wahkeena Falls: None of the landmarks in the original clue exist, so this box is in a totally new place, but still near the falls. Continue past the stone bridge to a trail junction. One direction--toward Multnomah Falls--is fenced off. (Has been for years. I'm skeptical if they'll ever reopen the trail.) Follow the stone wall in that direction. At the end of the stone wall, another more primitive type of stone "wall" begins. A stone wall with lots of large cracks and holes. Yep, the box is hidden in one of the holes. A couple of small rocks cover the opening.
