You can cycle across the top of the dam, which was constructed in 1928 to help control flooding in the region. It stands at 147 feet high, and today supports a myriad of outdoor recreation activities on the reservoir.

Great view of the Puddingstone Reservoir, a 250-acre man-made body of water. There is a road that runs along the perimeter of the reservoir and there is a spot to pull off the road to get a close up view of the water.

February 10, 2024, Brackett Field Airport

Hear a plane coming in for a landing? You're experiencing air traffic from Brackett Field Airport. This airport is over 100 years old; it was established in 1911 and is one of the oldest operating airports in the Los Angeles area. There are only two runways here, and this small airport is a hub for flight training schools, charter services, and recreational flying.
