Rocks and Fossils Field Trip

DATE: July 27th
TIME: 1:00PM
LEADER: Carl Buchholz
MEET-UP LOCATION: Kaner Flats Campground on the Little Naches Road. 
CONTACT: Carl Buchholz or 509-966-4861

The thundereggs are small but many have very high quality. Some have green areas and red veins in them with crystalline quartz centers. We will also stop along the way and look at plant fossils in road cuts. These sites are right next to the roads. The thundereggs are in loose soil at this location, so they are easy to dig and screen.

Tools to bring, if you have them: rock hammer, shovel, trowel, a three prong scratching digging garden tool, containers like zip lock bags to collect into, if you have a 1/4 inch hardware cloth screen bring it, some flat boxes like grapes are packed in to place fossil in, some pieces of carpeting, rags, old towels, or newspaper to place between the rocks to protect them when packed in a box, gloves, knee pads are nice, and water. You probably don't have all these things, but bring what you have. I have extra rock hammers, small picks, and army shovels that you can borrow.

I think that this will be a good field trip for children, because it is easy digging and they can find some excellent thundereggs and fossils.

Pleasant Valley Campground

Tree Health and Forest Ecology

We will gather at the day-use portion of the campground to meet Sean Tait, certified arborist and an expert on Northwest trees. As we walk along a paved one-mile loop trail through old-growth forest, Sean will help us understand the state of our forests and the unique stresses that impact individual trees in the forest. He will address both problems and solutions for cabin owners who live and deal with trees on permitted lots. We will also have a chance to view some of the very largest trees in the American River Valley.

Chinook Pass

Alpine Wildflowers of the Cascades

We will meet at the west end of the National Park arch for a walk along the Naches Peak Loop Trail at the top of the Pass to learn about some of the glorious variety of flowers that live in the subalpine regions of our local mountains. Naturalist and author Susan Summit Cyr will introduce participants to the plants that we encounter along this mostly level 3.5-mile loop trail. The views of Mt Rainier are unparalleled and we will also enjoy the many small ponds and other features that mark this trail. Members can participate in just part or all of the trail hike and should bring their own water, snacks, and sunscreen.

10 am-12 pm
Junction of Highway 410 and Bumping Lake Road

History of American Ridge Ski Bowl and other local landmarks.

We will meet in the parking area next to the information sign at the beginning of Bumping Lake Road. Susan Cyr, author of the history book, Tanum, will introduce participants to the time period in the past century which saw rapid development of recreational facilities in the local national forest. We will visit the American River Guard cabin and the American River Gaging station which is a CCC structure made entirely of stone. We will then drive up to the American River Ski Bowl and explore the site while learning about its unique and fascinating part in NW ski history.
