The picture was taken at a caldera, defined as an area where a volcano has collapsed into itself, and water has filled in where the earth was expelled when the volcano erupted.
If you dig a little at the surface, just a little outside the water's edge, the hole will soon fill with water that bubbles up from underground.
Here is the drill: Stripping down to a bathing suit put on before leaving the ship, the initiate runs across the sand, and dives into the water. Then beats a hasty retreat back to the pool and stays there for a minimum of ten minutes.
The water temperature was around fifty to fifty-five degrees, the air temperature about thirty-eight to forty degrees- quite mild for the South Pole, even in summer.

With the exception of a couple of scientific encampments and a very few buildings, there is nothing man-made on the entire continent. This allows you to enjoy the noise of hundreds of

As the expedition was ending, we were approaching the final port city of Ushuaia, Argentina. It was the last night aboard ship, and the crew threw a party for the passengers. All of

At some point in the evening’s festivities, I asked the captain if I could address the people in the room. He approved this and at an appropriate moment, I got up to speak.
I told everyone there how very much Nancy and I appreciated their willingness to accept us, wheelchair and all; how very thankful we were that they were so helpful, going out of their

And we returned the compliment by telling them Nancy and I both realized that without their assistance, acceptance, encouragement and support, we would never have been able to complete
what has come to be one of the most significant experiences of our lives.
When I finished my little speech, nearly everyone in the room was in tears... |
