Been going to the Clackamette park/Meldrum bar area some more and found some more nice agates. One thing Ive noticed on both the Sandy and lower Clackamas rivers is that the larger agates are almost invariably found up around the high water mark. Ive found a few smaller ones higher up on the gravel bars, but with only a couple of exceptions the bigger agates are further from the waters edge. Just an interesting thing to me. Might be helpful to others. See youse at the picnic.
