This scientific illustration depicts the typical burrow architecture of a woodchuck (Marmota monax), featuring a main entrance with a mounded soil pile, a secondary side entrance for escape, and an underground nest chamber lined with vegetation. A circular inset shows a top-down view of the main entrance mound, highlighting its irregular shape and surrounding vegetation. The burrow tunnels slope upward toward entrances to prevent flooding and aid ventilation.
