Bolsa Chica ecological reserve represents a victory of the environmentalists over the relentless effort of the developers to turn this area into a housing and business complex. A lot of work is still needed to be done in this reserve but it is coming along fine. The day I visited, the migratory birds were probably still on their way in or they already packed their bags and left for their seasonal destinations LOL. It was also low tide, so I did not see any fishermen trying their luck in areas where fishing is permitted. I saw a few bird watchers armed with binoculars and cameras fitted with powerful telephoto lenses but I did not see any subject of interest for them to photograph, at least while I was there.
Just beyond the wooden bridge, there used to be a lot of active oil wells but they have all been plugged off and abandoned except for a few. The oil deposit underneath (Huntington Beach oil field) is almost depleted now but with modern technology they are still able to wash off the oil clinging to the oil sands and extract them.
