PULLMAN — Cleanup efforts continue at the Illia Dunes recreation area on the Snake River near Pullman.
The area was closed on Monday after a crowd of some 3,000 people partied there last weekend. They left many broken beer bottles and other garbage.
The Army Corps of Engineers says it has cleaned up more than 3,000 pounds of trash and hundreds of styrofoam coolers. But much more trash remains.
The corps said it has not decided when the Illia Dunes will reopen.
The area typically receives 100 to 300 visitors on a weekend, and they are encouraged to take their trash with them.
The dunes are a popular recreation site with sandy beaches on the south shore of the Snake River about three miles downstream of Lower Granite Dam.
