Hi Rednick, you've probably been told this before, but I can't find where! Your placemarks for La Montaña de Taco in Renerife are slightly out of place. I've picked up several of them, one under "Google Earth Community (unranked)", and two of them under "Google Earth Community / Earth Browsing". They are out by a couple of miles, enough that I'm not the only one who hadn't connected the distant i icon with the actual feature! Afger has posted a link in "Huge and Unique" which sits right on the lake - but he didn't know what it was.
I'm only posting it, because I wondered what it was, and I was passing there last week.
