On Sat. Sept 14th we went over Chinook Pass to Little Naches for Thunder Eggs, Lily Pad Jasper and Leaf Fossils. We had 16 folks altogether in 6 vehicles. Weather was great. No rain. Lots of fun. I managed to load up a bucket from the thunder egg site, where we spent 3 hours. Then we moved to the lily pad site where I loaded up another bucket of material. And then on to the fossils for a short time. The mudstone where the carbonized leaf fossils are found is estimated to be about 35 MYA according to the state geology maps.
