JACKSON, Wyo. (AP) - No one can say when the mountainside collapsing into this Wyoming resort town will give way. But it appears increasingly likely that when it does, it's going to take a piece of Jackson with it.

Workers and residents have watched helplessly as the slow-motion landslide spanning hundreds of yards split a house in two and buckled pavement.

Standing at the edge of the rocky slope, Jackson Fire Chief Willy Watsabaugh said the earth movements slowed somewhat Saturday. That gives crews a chance to re-assess the damage, yet leaves an uncertain fate for the businesses, houses and two apartment buildings in the slide zone.

What triggered the slide remains under investigation. Authorities are looking into whether construction at the foot of the mountainside contributed.
