ENDANGERED SPECIES -- Rare sightings of at least four grizzly bears in "the wedge" of land between the Kettle and Columbia Rivers in northeastern Washington have been documented this week by Fish and Wildlife Department trail cameras.

Here's what the agency posted Thursday:

A number of grizzly bear detections have been reported just within the last ten days, including photographs of four different grizzly bears in the Wedge, Game Management Unit (GMU) 105. One of the photographs was of a sow and two cubs, which is highly significant for Washington State. Amongst response measures taken so far, District Wildlife Biological Staff Dana Base and Jay Shepherd have coordinated with relevant staff from other agencies having management jurisdiction, posted bear awareness signs at campgrounds and other suitable locations in the Wedge, and made telephone advisory contacts to spring black bear permit holders for GMU 105.
