The Antoine Creek Fire is in mop-up stage after crews contained the blaze yesterday after it burned over 65 hundred acres. Fire managers say crews completed the last piece of a fire break Tuesday night and they're confident it will not escape containment. A get-ready-to-evacuate warning for residents of about 50 homes in the Alta Lake area was lifted yesterday. Alta Lake State Park is expected to reopen Thursday. More than 300 firefighters have been building lines since the fire broke out Sunday in grass, brush and light timber. No structures burned. The cause is under investigation.
