Photo of the Week – Is that an Alien in Constitution Gardens Lake?
One recent morning during a National Mall bike ride, I spotted this alien looking National Park employee in full wet suit, gloves and gas mask walking chest deep in Constitution Gardens Lake, adjacent to the Reflecting Pool in front of the Lincoln Memorial.
She was spraying an algaecide from a long hose connected to a large truck-mounted feeder tank.
Single-cell blue-green algae (cyanobacteria) is a natural inhabitant of many of the pools, ponds and fountains around the National Mall.
The heat of the summer and abundance of sunlight promotes algae’s growth, so chemical must be used to keep the water clear.
