Filmmaker James Cameron will demonstrate his other hobby -- deep sea exploring -- in the District this week.

Cameron's Deepsea America tour is making a stop in D.C. on its way to the Woods Hole Oceanographic Institution in Massachusetts. Both Cameron and a semicradling Deepsea Challenger, the submersible he piloted to the bottom of the Mariana Trench in March 2012, will stop by Capitol Hill on Tuesday morning and park at Woodrow Wilson Plaza that afternoon, where Cameron will speak.

The Challenger will be on display for two days at the National Geographic Society on M Street. On Thursday, the "Avatar" director will be honored at National Geographic's annual Explorers Symposium and Gala along with BASE jumper Felix Baumgartner, "Jeopardy!" host Alex Trebek, oceanographer Sylvia Earle and philanthropist Howard Buffett.
