Our first stop on Tuesday the 26th was a beach on the north shore of Santa Cruz island. We started on this beach, and then walked to Las Bachas. On the way, we saw much wildlife, including our friend El Canario María:
Yellow Warbler
We saw our first of many Lava Lizards:

And the ever-present Sally Lightfoot Crab and Frigatebird:

Las Bachas beach is named after "las bachas" - remains of barges abandoned by the US at the end of WWII that floated to the beach and have remained there rusting ever since:

On the way back, we stopped by a salt lake where flamingos can be found (we did not find one). However, we did find other things, including a Marine Iguana bathing:

Various shorebirds were in and around the lake:
Black-necked Stilts

Sanderling and Plover

We returned to the original beach, where many of our party went snorkeling. Jill and I, however, stayed on shore to watch birds and other wildlife. We were rewarded! Many Sally Lightfoot crabs:

A nice little Lava Heron (I think):

Our first Galápagos Flycatcher (we would see more on a subsequent island):

Once everyone else was done snorkeling, we returned to the ship:
MV Origin
We got underway while we lunched:
Before we disembarked, I watched our hard-working crew unload a Panga. Much activity like this went on behind the scenes and we were not generally aware of it as passengers. This is sped up 6x.
Our destination for the afternoon was Cerro Dragón, "Dragon Hill", named because it looks somewhat like the head of a Land Iguana from some angles. Here it is from the beach:

On the beach and the early part of our hike we found more of our friends the Marine Iguanas:

There were Boobys diving for food:
I found bumblebees in the foliage:

And we found more Sanderlings:

As well as our sentinel, the Mockingbird:

It was a warm day, and the hike was through desert terrain. Always bring water and wear sun protection!

We were on the hunt for Land Iguanas. We found evidence of their existence, including tracks and a bone:
Land Iguana tracks (with people tracks)
Iguana Vertebra
And then we found what we were looking for - a nice big Land Iguana. Very different from the Iguanas seen on the mainland:

We saw five or six land iguanas that day.
We made it to the top of the hill and I stopped to take a panorama:
I got two GoPro Hero3 Black cameras and am planning a panoramic project with them. However, to do the project correctly and accurately, I need a good read on their field-of-view. So, I set up a tripod and a grid and a tape measure, and took a few photos. Here they are, desaturated and contrast-enhanced, with central red dots and some annotations. First, measuring the diagonal FOV: Next, the horizontal FOV: Finally, the vertical FOV: The front of the camera lens was almost exactly 17 inches from the grid. The camera body started about 17.25 inches from the grid. Assuming the sensor is embedded some distance into the body, I used an estimated field-to-sensor distance of 17.5 inches. This yields the following field-of-view, in degrees: Diagonal: 146 Horizontal: 121 Vertical: 93 Doing a little interval math on the field-to-sensor distance shows these angles are accurate to about plus or minus 1.5 degrees.

I got up this morning very early to make an animation of Jupiter, Mars, Saturn, the Moon, Venus, and Mercury as they rose in the early morning sky. Here is the finished product: It was very cold - 7 degrees Fahrenheight - and very early. This is a 30-minute sequence starting at 5:39 AM and finishing at 6:09 AM. All of the images have the same parameters: Canon 7DmkII camera Canon 8-15mm f/4L lens, locked at 10mm (widest useful zoom with this lens on a 1.6x crop camera) 8 second exposures at ISO 3200 Image sequencing performed by Canon's EOS Utility. A capture was started every 15 seconds. That camera/lens combo yields a 180-degree diagonal field-of-view. Jupiter and Mercury are about 120 degrees apart in these images, so this gives some extra room for animation and cropping. Capturing all five planets in the pre-dawn skyglow is surprisingly tricky, especially when city light pollution is contributing to a murky lower atmosphere. ...
A few years ago, I converted various planet maps to icosahedral models . You can print these out, cut along the solid lines, fold along the dotted lines, and have a nice icosahedron to play with. Since then, two more robot spacecraft have created global maps of planetary bodies. Most recently, the New Horizons spacecraft flew past Pluto. Here is an icosahedral projection of the data we have so far: Also fairly recently, the Dawn spacecraft has orbited both Vesta and Ceres, two of the largest asteroids (or "dwarf planets" as the new nomenclature has it) in the Solar System. Here are icosahedral projections of those two. First, Vesta: Next, Ceres - note the mysterious white spots toward the upper right: All of the data used to create these projections was taken from Steve Albers' Planetary Maps Page , which I highly recommend. Edit: A PDF file of helpful hints on assembling these can be found here .
