Photographing
The Pinnacles Geologic Site is a top destination for photographers who like capturing the unique side of nature. Considered very similar to the Pinnacles National Park in California, this site features hundreds of pinnacle rock formations. These pinnacles were estimated to have been formed between 23 to 100 million years ago when underlying volcanoes released masses of molten lava on the earth's surface. The pyramid-shaped structures we see here today are the result of the lava slowly drying and hardening to create a structure. These pinnacles exist at this site beside other structures, like eroded sandstone formations, and make for a great backdrop to photograph while on a hike, bike ride, or horseback excursion.
Wildlife Viewing
Another factor that makes The Pinnacles Geologic Site so unique is that it is a nesting and breeding ground for the ferruginous hawk. The nesting season for this hawk begins in late March to early April, so it's likely that you'll see these birds in the area if you visit during the spring. Some mammals native to this area include elk, moose, deer, mountain lions, black bears, and bison.
Picnicking
While there are no picnic sites for you to use at The Pinnacles Geologic Site, you are still permitted to bring your own chairs to create a picnic spot in the area so long as you also bring trash bags and pick up after yourself. You can also use nearby picnic sites, such as the Pioneer Trails Picnic Grounds, which is a picnic area with multiple tables and a pavilion near Green River. You could also check out Centennial Park, which has a picnic gazebo and a playground.
Stargazing
The Pinnacles Geologic Site is far from city lights, so it experiences some very dark night skies. Consider taking advantage of this darkness by staying overnight in the area and stargazing, which you can do by tent, RV, or even backpack camping at the site. Keep in mind, though, that, even though the days in the summer here are quite hot, Wyoming experiences chilly to freezing temperatures at night year-round. That being said, if you plan on stargazing at this geologic site, be sure to pack warm layers and non-electric heating equipment.
