Lake Martin is part of the Cypress Island Preserve operated by The Nature Conservancy. Located in southern Louisiana, Lake Martin is primarily known as a bird sanctuary, but like most swamps in the region, it is also well populated by alligators.
The road alongside Lake Martin is lined mostly by mature cypress trees in shallow water, so there are very few places where visitors can see open water from the road. If you are lucky, from one of those open spots you might see an alligator cruising along as in the above photo. More commonly, alligators are sighted lounging amongst the swampy shallow water adjacent to the road.
(I guess I could have waded in and removed the large Sprite bottle to make a better photo, but I decided instead to leave the bottle there as a scale indicator.)
This gator above was so impressive that I zoomed in for a portrait shot. If you look closely you can see one of its cuspids hanging over its lower lip.
When it is sunny, alligators seem to enjoy relaxing on cypress logs. When crawling up to the log, they often carry floating vegetation with them as this one did.
Young alligators also enjoy sun bathing on logs, sometimes individually,
and sometimes in groups.
