The autumn cavalcade of special events in the East Bay Regional Parks continues Sunday with the Stone Age Olympics and Knap-In at Coyote Hills in Fremont.

From 10 a.m. to 4 p.m. you can try your hand at lots of prehistoric life skills such as dart throwing and fire starting under the guidance of naturalist Dino Labiste. You can also watch skilled knappers turn rocks into functional tools. It all takes place at the park's Dairy Glen campsite.

Coyote Hills is at 8000 Patterson Ranch Road, off Paseo Padre Parkway. The event is free, though parking is $5. For information, call 510-544-3220. Dino also will preside over two ancient skills programs at Coyote Hills on Sept. 28. There's a fire-making clinic from 9:30 a.m. to 12:30 p.m. and an atlatl dart-throwing session from 2 to 4:30 p.m. The fire-making program is for ages 16 and older. It's free, but registration is required. Call 888-327-2757. Select option 2 and refer to program 3456.

Atlatl practice is also free, and no registration is required. It's for ages 8 and older; meet at the Hoot Hollow picnic area. Hoot Hollow is in the back of the Visitor Center, along the Quail Trail. Look for the sign or ask in the Visitor Center.

Camp under stars: There's a fun-sounding overnight campout scheduled on Oct. 19-20 at Lake Del Valle, south of Livermore, that's part of the park district's "Living With The Earth" program series.

Led by naturalist Cat Taylor, the group will gaze at the full moon and Orionid meteor shower and gather around a campfire. Campers supply gear and a potluck dish; there's a ¾-mile walk to the campsite with shuttles available for gear transport. The program costs $18 ($20 for nondistrict residents), and registration is required. For registration and information, call 888-327-2757. Select option 2 and refer to program 3717.

night hike: Watch day turn to night and learn about nocturnal animals during an easy hike from 6:30 to 8 p.m. Tuesday at Briones Regional Park near Orinda, led by naturalist Trent Pearce.

It's free of charge. Meet Trent at the East Bay Regional Park District's Bear Creek staging area on Bear Creek Road about 5 miles east of San Pablo Dam Road in Orinda. Bring a flashlight. For details, call 510-544-2233.

WALK IT: The Wednesday Walkers will take on Brushy Peak near Livermore for a 4- to 5-mile moderate-to-strenuous hike at 9:30 a.m. Wednesday. This is a good chance to see a golden eagle. They like it out there, and I've seen an eagle almost every time I've visited the park.

To get there, take the Vasco Road exit from Interstate 580 in Livermore. Head north toward Brentwood but, immediately after the 580 overpass, turn right on Northfront Road. In about a mile, turn left on Laughlin Road and drive to the end. For details, call 888-327-2757, ext. 3241.
