In 1972, M. Eloise Battle led the charge to save Tecolote Canyon, alongside her neighbor, Sherlie Miller. They became known as the “Tecolote Twins,” and today, their passion for this special place has persisted.

Centuries ago, the Kumeyaay, native inhabitants of the area, found food and shelter in Tecolote Canyon. In 1957, City officials proposed opening a sanitary landfill on the site. The proposal was eventually dropped due to opposition from Linda Vista and Clairemont residents. 

In the 1960s, as land became scarce, builders proposed adding 1,500 apartments and homes and adding a major four-lane road. Community residents, who had long enjoyed the beauty of the canyon, took action to save Tecolote Canyon as an open space park. Because of Battle and Miller’s determination, in 1974, the San Diego City Council formally established an assessment district for Tecolote Canyon and voted a one-time tax for homes sloping into the canyon at $775 each, while homes across the street were taxed $175 each. With the help of their neighbors, the women and their supporters were able to save Tecolote Canyon for future generations.  

The City of San Diego eventually acquired the land and reimbursed the residents. On April 1, 1978, the park was officially dedicated and named Tecolote Canyon Natural Park. During the dedication, the first members of the Tecolote Canyon Citizens Advisory Committee were sworn in. With the support of City Park Rangers, dedicated community members continue to work together to preserve and protect the canyon's natural beauty. 

Thanks to the Tecolote Twins, residents can enjoy Tecolote Canyon Natural Park and Nature Center, which offers a variety of educational and recreational opportunities. The Canyon includes approximately 6.5 miles of trails that can be used for respite, reflection, walking, running and mountain biking.  

Battle remained a dedicated advocate for Tecolote Canyon throughout her life, continuing to protect and support the space she helped save. She passed away on March 28, 2025, leaving a legacy of commitment, advocacy and lasting impact.
