  The Hart Tree is a Giant sequoia (Sequoiadendron giganteum) tree within the Redwood Mountain Grove, in the Sierra Nevada and Fresno County, California. The Redwood Mountain Grove is protected within Kings Canyon National Park and the Giant Sequoia National Monument. It is the 25th largest giant sequoia in the world, and could be considered the 24th largest depending on how badly Ishi Giant atrophied during the Rough Fire in 2015.
  
  ## Description
  
  It was once claimed to be the fourth largest Giant sequoia in the world, but is now considered the 24th largest. It has a volume of around 980 cubic metres (35,000 cu ft). Hart is located 37 m (121 ft) north of Roosevelt, a slightly larger giant sequoia with a volume of 991.5 cubic metres (35,010 cu ft).
  
  The tree was named for Michael Hart, who discovered it sometime around 1880.
