September 2012. The water levels are low because we've had a dry summer in the rain forest of Western Washington. One of my very best friends was willing to hike into Denny Creek near the summit of the Cascade Mountains and look for grossular garnets and quartz crystals. Dad loaded up the backpack, and we were off. You can see a picture of the large boulder and the garnets that we found under the Washington State section. Here, however, are a couple of pictures of us in the Denny Creek rock canyon.
