|Devonian Fossil Gorge Entrance Plaza|
There are displays in the Entrance Plaza about the fossil bed. In 1993 heavy rains filled the reservoir. Water spilled over the spillway (I guess that's what spillways are for) for at month at 17,000 cubic feet per second. It washed out the road and the campground (no campers were damaged during the making of the gorge) and scoured the soil and sand down to bedrock and beyond. As the waters receded, there was clear evidence of the lake bed and the plants and animals that existed here during the Devonian Period. In 2008, there was another flood (and I thought it rained a lot in Seattle!) which washed away the huge boulders left from the first flood.

I found these in the ledge around the gorge.
Sometimes I'd find the number, and couldn't find the fossil it was describing. Descriptions in the Key were definitely ambiguous scavenger hunt clues. Phrases like "6 feet north", "near this point", "around this area" made the search even more like looking for treasure. These are a kind of colonial coral called Hexagonaria.
In some places there are so many fossils I couldn't figure out which ones the Key is referring to. That goes back to not paying enough attention to the descriptions of the fossil types up by the displays. I think these might be brachiopods.
