BOISE, Idaho (AP) — The Idaho Outdoor Business Council has sent a letter to President Barack Obama urging him to use his executive power under the Antiquities Act to create a 592,000-acre national monument in a rugged swath of central Idaho.

The coalition of 45 business and recreation groups says in a statement Wednesday that designating the 592,000-acre national monument would increase protection of an unspoiled area for current and future generations.

Another plan proposed by Republican Rep. Mike Simpson of Idaho is to create three wilderness areas totaling 332,775 acres while also releasing 130,000 acres from a wilderness study area to a multiple-use designation.

But that plan for years has failed to get through Congress. So some groups are asking Obama to create a national monument instead.
