Investigate the geology of the Bruneau Fossil Reef and Horse Hill Site with guide Steve Schaps. Two stops will include:

1) The Horse Hill Site which includes a large unconformity surface between the Miocene and Pliocene and lots of fossils, petrified wood, and Moqui Balls. This will also be our lunch stop. Hiking distance is ~1/3 Mile with the option to extend to ~1 Mile. A short 5-minute geologic presentation will be made on-site.

2) Fossil Algal Reef site, which includes a ~1/2 mile hike along a fossil reef full of algal “Vases”, snail fossils, and other types of interesting geologic features and fossils. A short 5-minute geologic presentation will be made on-site.

We will meet in the Albertson’s Shopping Center parking lot at 10am near McDonald’s Restaurant, 6574 S Federal Way, near the intersection of I-84 and Hwy 21. From here Steve will facilitate carpools. We will need some people with higher clearance vehicles to be carpool drivers, especially people with Trucks, 4WD, or AWD vehicles. If necessary, we can take passenger cars and Steve can ferry people back and forth the last mile in his 4WD truck. Max 5 cars, so plan on combining people into fewer vehicles.

The first stop is roughly 80 miles from the meetup location on Federal Way. We will stop at the “One Stop” store and gas station in Bureau to regroup. Steve will have driving directions, GPS locations, and a map ready to give to volunteer carpool drivers. Not much hiking involved ~1 mile the entire day. Suitable for almost all ages and abilities. Wear suitable shoes for some uneven ground. Limited to 16 people and 5 cars because of rough road and parking.

Bring lunch and beverage. No restrooms but that has never stopped us. Dress for the weather, including proper shoes or boots. Return about 4pm or so. No dogs, please.

This event will be cancelled if there is measurable snow, rain or high winds. No charge if the IMMG cancels the event. Please check your email the day before. Be sure you register with a functioning email.

Everyone must pre-register. https://www.eventbrite.com/e/bruneau-fossil-reef-geologic-field-trip-tickets-1087161682859
