Our Story

From illegal dumping ground to forest treasure.

NEGLECT, FIRES, NEW TREES

Heaps Peak Arboretum was not always a haven for trees, shrubs, flowers and wildlife. In the late 1800s, Fred Heaps owned a ranch on this location. When he died, his nephew built a lumber-harvesting operation—an ironic use of land that would ultimately become the Arboretum.

In 1922 a huge fire devastated the area, and only blackened trees remained. Six years later, the Lake Arrowhead Women’s Club, headed by Mary Putnam Henck, organized the first planting of new trees.

Club members and students from Lake Arrowhead Elementary School assisted in the project. In 1931 the site was officially named the Heaps Peak Reforestation Project.

All of the planting stopped, though, with the onset of World War II. There was another fire in 1956 and, sadly, the land then became an illegal dumping ground. It would remain in that sorry state until the early 1980s.

VOLUNTEERS TRIUMPH

Fast forward to 1982! Community member and revered schoolteacher George Hesemann was very disturbed by the neglect of this forest treasure, so he assembled a group of volunteers to create the Rim of the World Interpretive Association (ROWIA). 

George Hesemann (1929-1998), founder of ROWIA, was a highly respected local teacher whose passion for nature in general and the San Bernardino Mountains in particular inspired countless students over the years.

Together, members of the determined group cleaned up the site, created the Nature Trail and, eventually, a shorter wild-animal-footprint trail (especially for kids), and planted 175 new trees. Heaps Peak Arboretum opened on June 30, 1984.

Today, the founders’ legacy lives on. Volunteers still take care of the 30-acre site, including tending plants and adding new ones, cleaning public areas and maintaining the trails to ensure that Heaps Peak Arboretum will be enjoyed by many generations of nature lovers to come.
