Caswell Memorial State Park
Caswell Memorial State Park is experiencing a phenomenon known as Summer Branch Drop. The term describes the failure of mature tree branches in summer, with no obvious cause. The failure of trees is inherently unpredictable.

The Native Americans who lived along this river and collected acorns among these ancient groves were Yokuts. In the early 1800s, Spanish explorers traversed this area, and fur trappers found the river bountiful.
Thomas Caswell, landowner, enjoyed this wonderful forest and felt it should be preserved. In 1950 the children and grand children donated 134 acres to the people of California. Additional donations and state purchases brought Caswell to its current size of 258 acres. Caswell Memorial State Park was open to the public in 1958.

The Stanislaus River meanders through the park, with beaches and swimming areas near the park’s day use and campground facilities.
One of the most magnificent aspects the park has to offer is its seemingly endless nature trails. The trails allow a glimpse of what the riparian ecosystem of the valley would have looked like in pristine times. A majestic Oak Forest is surrounded by many other lush plant species, some of which are rarely found anywhere else in the area.
The park offers a rich variety of wildlife viewing. While many of the wildlife species here are nocturnal and rarely seen, bird watching is a favorite among nature lovers. Red shouldered and red tailed hawks are often seen, along with dozens of other winged artists.
