Full-size (for full effect). Basaseachi is a 312 meter waterfall.

I didn't find a great picture of these on the Web. The couple below are a start. The link describes them a bit. Apparently the waters are charged with calcium and carbonate, so that the mineral is precipitating and forming dams while at the same time the water flow is eroding the dams. Very interesting! Historically, this is where the first shots of the Yugoslavian splintering war were fired. Plitvice Lakes are a UNESCO World Heritage site. This last one is reduced size (and the left side is clearly taken from the same vantage point as the one above). Click...

You may have noticed that ever since discovering Iceland's Skogafoss that I'm a little fascinated with waterfalls in a columnar basalt terrain. Well, I like waterfalls in just about any terrain, but I like the unusual combinations that occur in volcanic terrains. One of the ultimate examples is Tower Falls in Yellowstone, of which images abound. I looked and looked for 4-5 minutes to find a nice one, but there may be better. This one may take a few moments to load: The towers are eroded tephra. On the opposite side of the canyon from Tower Falls, there is columnar...

Some background; in the last couple of weeks, I've been posting pictures of "Great Falls", starting with the Great Falls nearest to me, on the Potomac River. I speculated that there are several "Great Falls" around (there are). A humorous wag posted that one of them must be the "Great Falls of Bire" (rim shot, please). I replied to him that if Ireland had a great falls, this would be the "Great Falls of Eire". So I Googled to find out if Ireland had a great falls. It doesn't, but in searching, I discovered the "World Waterfall Database", which right...

Due to unexpected circumstances, I wasn't able to post a Geopic of the Week for the last week of September, so I'm making up for it now. Here's the picture I was going to post for the last week of September (click on this reduced size version for the full size shot): Victoria Falls photographed from the Space Station Victoria Falls holds the record for being the longest "sheet" of falling water in the world. This got me wondering; what's the second- longest? I guessed either Niagara Falls or Iguazu Falls. So I did a search on Google with "Niagara...

But she didn't turn to them late that Saturday night in June 2000 when she wanted to go out and couldn't find anyone to watch the toddler. So she took him to a footbridge over the Passaic River in Paterson and  tossed him into the water just above the Great Falls. Yesterday,...

After having fun with Taughannock Falls in New York a couple of weeks ago, here's a similar (and actually more famous) waterfall. Shouldn't be too hard to figure this one out. There are much better pictures of this waterfall on the Web, but they were labeled and gave away the location.
