The park's lodging concessionaire late Saturday announced it is scaling down operations for the rest of the 1988 summer season because of fires that have created smoke problems and unpredictable road closures.

Steve Tedder, TW Recreational Services general manager, said it has become necessary to scale down concession operations in the Lake, Old Faithful and Tower areas of the park.As of Monday, only these facilities will remain open: Lake Lodge in the Yellowstone Lake area; Mammoth Hot Springs Hotel and Cabins in the northern portion of the park; and Old Faithful Inn in the Old Faithful area.
