Shoofly Oolites: Landscape of Mars at Shoofly Oolite Interpretive Trail Site – Grand View, ID

The Shoofly Oolite area is a geologic wonderland located about 70 miles away from Boise near Grand View Idaho. It's probably the closest you can come to hiking on the surface of Mars.

This is a BLM site and includes a few signs and a small parking area and lots of weird rock formations, caves, holes, arches, and bathtub features, which are interesting to everyone. Steve Sawyer will begin with a short geologic presentation at the entrance of Shoofly.

Oolites are rocks made up of small round calcium carbonate deposits (not sand), which look like tiny (BB-size) eggs. The hike is about 2.5 miles total and of moderate difficulty involving "uneven ground, loose sand, and travel over rock ledges, and loose sandy slopes".

We will car-caravan to our destination. Please carpool as much as possible. Paved roads the entire way. Return to Boise around 3 pm.

WHAT TO BRING

Bring lunch and beverage. No restrooms at Shoofly but sagebrush is big. Dress for the weather, including proper shoes or boots, and be prepared for light wind and snow.

No dogs, please. The area is fragile and we want to treat it with a light touch.

Event will be cancelled if there is measurable snow, rain or high winds. You will receive a full refund if the IMMG cancels the event. Please check your email late the day before because that's how you'll learn if the field trip is canceled. Be sure your email address is functioning.
