Accessible SymbolMuseum

Four paved parking spaces are reserved on an average 2.4 percent sloped lot directly in front of the museum. The curb cut is at the lower end, where a paved pathway leads to the entrance. The entrance pathway has a 7.5 percent slope, 36-feet long and has no handrails. The entrance is level with easy-to-open doors. Inside the entrance to the right is a staffed information desk where they take admission fees and offer books, postcards, t-shirts and mementos for sale.

To the left of the entrance is an accessible water fountain. Around the corner are the men’s and women’s restrooms, both with lever-handled lavatory faucets, an accessible baby-changing table and front-transfer toilets. 

Exhibits include glass cases, wall-mounted panels and hands-on specimens. All exhibits have interpretive panels. A video is shown in the auditorium with closed caption available. Interpretive programs are available for organized groups by reservation.

Wildflower Trail

The trailhead is located near the top end of the reserved parking. Here, a kiosk provides site information and an accessible water fountain is located nearby. The paved portion of the trail becomes very steep and ends at the lower museum door, which cannot be used from the outside. From here, a gravel back-filled flagstone trail continues with a rope railing. Reaching the bluff, a series of railed steps interspersed with stretches of fine-gravel lead to the bottom. The trail continues in gravel fines through the bone beds and in a loop up the slope, past a historic quarry and back to the trailhead.

    This one-half mile long trail is level with a packed base of gravel fines or earth and is considered accessible. Fair weather should find the base solid. Level access can be found by going past the shelter house.
