six months into his second term as president. The U.S. Congress made the name Mount McKinley official in 1917.

Native Alaskans were insulted (侮辱) by the name change. The result has been a political tug-of-war between Alaska and Ohio. Since 1975, Alaska politicians have pushed Congress to change the name back to Denali. Now that President Obama has changed the name, some people in Ohio are very unhappy. "This political change is insulting to all Ohioans," said Congressman Bob Gibbs, who is from that state.

Denali also made news this week for another reason: U.S. officials decreased its official height by 10 feet. The United States Geological Survey announced that Denali is 20,310 feet high, not 20,320 as previously thought. The mountain has not shrunk. Advances in technology allowed scientists to take more accurate measurements of it.
