Even with traps set and flyovers in the area of the incident, Yellowstone National Park biologists have not located the bear involved in last week's fatal grizzly attack.
A release from the park Friday afternoon said that there have been few bear-sightings by biologists in the week since they have started their search.
Last Friday, Aug. 26, body of 59-year-old John Wallace of Chassell Michigan was found along Mary Mountain Trail, and autopsy determined Wallace had died a day before from his injuries sustained during a grizzly attack.
The release also said that Yellowstone expects big crowds for Labor Day weekend, so reservations are recommended.
Some services do begin to close Sunday Sept. 4, so visitors should obtain a copy of park handouts at entrances. Information can also be found at Yellowstone's website.
All roads in the park are open, and the fire danger remains "High".
