Crews in lower Old Town excavating a site where two houses will be built found human remains on Monday and archeologists on Tuesday continued to search for bones.

The site, between the 1200 blocks of Empire Avenue and Norfolk Avenue, was roped off with police tape as police investigators, archeologists and machinery operators were at work.

The police say that they are not treating the site as a crime scene. Rick Ryan, a Park City Police Department lieutenant, says the police received a call at about 2:30 p.m. on Monday that a human skull was discovered.

Officers initially launched a criminal investigation but Alan Siddoway, Summit County’s medical examiner, determined that the skull was likely an antiquity. The police at 3:30 p.m. notified state anthropologists, who remained at the site on Tuesday.

Ron Rood, a state archeologist, says that such finds are common in Utah. He says the forensics investigation could last a few months.
