Pretty weird article. Just on the title alone:<p>- 'Mysterious': there's very little of substance in the article to advance the position that it is mysterious at all.<p>- 'Sacred': OK, I guess!<p>- 'Pyramid': "A fourth explanation — one for which there is no evidence — is that Cerro El Cono sits on the ruins of a pyramid built by ancient Indigenous tribes". So... no evidence then :)<p>- 'Hidden': "It rises steeply from the relatively flat jungle landscape of eastern Peru, making it visible from as far west as the Andes — 250 miles (400 kilometers) away — on a clear day."
