Emergency Officials Say Landslide Is Slowing in Movement

Officials with Yakima County Emergency Management continue to monitor the Rattlesnake Hills Landslide in Union Gap. And they say it continues to slow in movement. The latest measure shows the slide now moving at .45 feet per week and as slow at .006 feet per week.

The slide was first reported in 2017 and ever since local and state officials have been watching and monitoring the slide that experts say could take years to finally collapse. In 2017 the concern about falling rocks pushed officials to place cargo containers along the base of the mountain to prevent to rocks from impacting traffic along Thorp Road which is now closed. Officials with the office of emergency management recently flew a drone over the slide area. The footage is being shown on the YCEM Facebook page.
