At low tide, the estuary is known for its dangerous mud flats made of silt created by glacier-pulverized rocks. At least three other people have gotten stuck and drowned there over the years.
Many more have been rescued, including someone who was fishing there last month."It’s big, it’s amazing, it’s beautiful, and it’s overwhelming," Kristy Peterson, the administrator and lead EMT for the Hope-Sunrise Volunteer Fire Department, said of Alaska.
