HPWREN Reflections by a Future Scientist

The following article was written by 12 year old Rachel Donahue, a 6th grade student at Double Peak K-8 school in San Elijo, and granddaughter of HPWREN staff member Greg Hidley. A separate article with the meeting presentations should be available soon.


On April 4, 2019, my grandpa invited me to his HPWREN users meeting. HPWREN is a microwave linked camera system that sends and collects data to many organizations. As a young viewer, I was most interested in how HPWREN helped Caltech Palomar Observatory and the California Wolf Center.

I was most interested in the Palomar Observatory because I would like to be an astronomer when I grow up. I learned how the cameras on Mt. Palomar can send and collect data to the California Institute of Technology.

2018 Restoration of Big Black Mountain HPWREN and ALERTSDGE Instrumentation and Radio Relay Site

Black Mountain is a summit in the Cleveland National Forest of the Peninsular Ranges in eastern San Diego County, California, north of Ramona. It has been a key observation, relay and meteorological site for HPWREN since its early 2013 installation. The peak is measured at 4,048 feet (1,234 m), and is sometimes referenced as Big Black Mountain to distinguish it from the smaller Rancho Peñasquitos Black Mountain Open Space Park in the city of San Diego (west of I-15). Black Mountain is also home to one of the largest remaining tracts of the threatened Engelmann Oak (Quercus engelmannii).

On January 28, 2018 a significant Santa Ana wind condition impacted San Diego County, and with it came substantial damage at about 10:08 AM to the Big Black Mountain relay site north of Ramona. The relay site supported a link to the HPWREN backbone site on Mount Woodson, and connected a firefighting
agency site.
