This is so incredibly sad
Approximately 191 feral horses have been found dead in a stock pond on Navajo land in northern Arizona, according to Navajo leaders, who attributed the death to ongoing drought and famine.
"These animals were searching for water to stay alive. In the process, they unfortunately burrowed themselves into the mud and couldn't escape because they were so weak," Navajo Nation Vice President Jonathan Nez said in a statement on Thursday.
Some of the horses were found thigh- to neck-deep in the mud at the stock pond in Gray Mountain, according to Nina Chester, a staff assistant for the office of the president and vice president.
