Spanish archaeologists say they have discovered an exceptional set of Paleolithic-era cave drawings that could rank among the best in a country that already boasts some of the world's most important cave art.

The pity is that almost no one is going to get to see them.

Chief site archaeologist Diego Garate said Friday that an estimated 70 drawings were found on ledges 300 meters (1,000 feet) underground in the Atxurra cave in the northern Basque region. He described the site as being in "the Champions' League" of cave art, among the top 10 sites in Europe.

The engravings and paintings feature horses, buffalo, goats and deer, dating 12,500-14,500 years ago.

But Garate said access to the area is so dangerous it's not likely to be open to the public.
