Visitors take photos at Mather Point in the Grand Canyon in this 2019 file photo. More than 6 million people a year visit the Grand Canyon, pumping $1.2 billion into the region's economy, another reason the park should be protected by a mining ban, backers of the proposal say.

The House voted Friday to permanently ban new mining claims on more than 1 million acres around Grand Canyon National Park, with supporters calling protection of the landmark canyon a “moral issue.” The bill would make permanent a current mining moratorium that is scheduled to run through 2032.
