Spanish treasure that predates the arrival of Columbus by 200 years has been found in a US national park.
The two coins, one minted in Madrid in 1660 and the other made around the 1200s, were found lying on the floor at Glen Canyon National Recreation Area, Utah.
Their presence in the desert remains unexplained and no information has been released about whether they were found with other artifacts.
Spanish explorers arrived in Mexico in the 1500s and began exploring north, although there is no record of them being in America at the time the coins were made.
Archaeologist Glen Harmon, from the national park service, said: 'A visitor was hiking in one of the canyons around here and he found these two strange things.'
He took them home and, after realizing they were old Spanish coins, returned them to the park.
