A foggy and cold morning in the cypress swamp in the Texas. This was captured in the middle of a lake from the boat. The bald cypress trees have a peculiarity of growth called cypress knees, which are the woody projections from the root above the ground or water. They were once thought to be providing oxygen to the roots, but the evidence for this is scant. A more likely function is structural support and stabilization, make the bald cypress strong enough to resist very strong winds and even hurricanes rarely overturn them!
