Monday (04-November-2019) — New Jersey

Indoor Nature in New Jersey.

I have noticed that when I make ice cubes using deionized water using a Zero Water purifier, “ice spikes” are often formed.

Thirteen-Years Ago (31-August-2006) — Wyoming

Gone to See America 2006 Driving Tour. Day 6: Mineral Hot Springs State Park, Wyoming.

While driving across Wyoming, I saw the sign for the “World’s Largest Mineral Hot Spring” painted in large white letters on a hillside. I decided to stop at the state park for a visit. Images taken with a Nikon D200 camera and 18-70 mm kit lens. All of the images have been reprocessed with current software (Topaz JPG to Raw and Capture One Pro).

Seven-Years Ago (30-August-2012) — North Atlantic Ocean

Gone to see Europe. Semester at Sea. Fall 2012 Semester Voyage on the MV Explorer. Day 08: At Sea, North Atlantic Ocean.

The early dawn sky was full of pink jet contrails when I got out on deck. The contrails would be from all of the red-eye flights crossing the Atlantic ocean from North America to Europe. A sign we were getting close to the end of our first leg at sea. As the sun came up, the contrails changed from pink to yellow.

Ten-Years Ago (30-August-2009) — Alaska

Gone to See North America Road Trip. Day 09: Alaska Marine Highway on the MV Columbia (Ketchikan, Wrangell, Wrangell Narrows, Petersburg).

Overnight we transitioned into Alaska waters. A little bit of rain for those sleeping on deck. Our first stop was in Ketchikan, where there were already three giant cruise ships. Some passengers got off at this point. The next stop was in Wrangell. I bought a $7 garnet crystal. Apparently, the owner of the mine near the town gave it to the boy and girl scouts so they could earn money selling the crystals to tourists. We then passed through the Wrangell Narrows Channel, a narrow passage with about 60 channel markers. The final stop for the evening was Petersburg, before continuing on overnight.

Gone to See America August 2010 Road Trip. Day 6: Eastern Sierra Photography Workshop with Michael Mariant. Mono Lake.

The first stop of the morning was to Mono Lake to view the Tufa towers at dawn and in the early morning sunlight. We had to leave Bishop well before sunrise to get there, even then we were a bit late.
