Las Vegas is making a pitch to have an area including fossil beds northwest of Las Vegas designated as a national park.
A Clark County spokesman says commissioners endorsed the idea last week and officials say Las Vegas and North Las Vegas are expected to take similar action this week.
Dubbed the Upper Las Vegas Wash, the area is more than 10 miles northwest of downtown Las Vegas.
Local officials cite fossil finds from the Pleistocene age and the work of scientists in 1962 who catalogued the remains of ice age mammals such as the Columbian mammoth, American lion and ancient horses.
No word on whether any mobster remains may be there.
The legislative resolution asks Congress to designate the area a national park with visitor facilities and working field sites where the public could observe scientific research.
