"The energy-rich diet of Lake Clark's coastal brown bears allows the largest males to reach weights exceeding 1,000 pounds by the time they enter the den to hibernate. Most adult males typically weigh 600-900 pounds by mid-summer, while females average 1/3 less in weight. This is carried on a frame 3-5 feet tall at the shoulder and 7-10 feet in length."
