BOISE -- The executive director of the 2.4-million-member Sierra Club says the chances of a national monument being designated in central Idaho are better than 50 percent.
Michael Brune on a stop in Boise on Thursday said he's met with Interior Secretary Sally Jewell to discuss a 591,905-acre national monument in the rugged Boulder and White Cloud mountains.
Brune says stalled legislation to create a wilderness area is why tens of thousands of club members are working for monument designation.
The group had a similar game plan leading up to the designation in May of a national monument in southern New Mexico.
President Obama vowed during the signing ceremony for the Organ Mountains-Desert Peaks National Monument to make more proclamations using his executive power under the Antiquities Act to protect federal lands.
