Geysir

Posted on May 16, 2014 by geek

Day 3 in Iceland. We did the Golden Triangle today. I’ve decided to post photos separately because there are just too many. Iceland is just amazing and amazingly beautiful. So first post today are from Geysir. Geysir, the original geyser from which all other geysers are named, actually rarely erupts. However, there are several other geysers and hot spots near it, and Strokkur does erupt quite frequently.

Heimaey, Iceland

Posted on May 15, 2014 by geek

Day 2 in Iceland. We drove to Landeyjaharbour to catch the ferry to Heimaey. Generally tourists, including us, go to Heimaey to try to see puffins. Unfortunately we seemed to have visited the island too early in the season. We took a cruise around the island but didn’t see any puffins. However the island is beautiful, and the terrain is impressive, all of which is a result of the volcanic origin of the island. On the south side of the island, the effects of the 1973 volcanic eruption are evident. I am disappointed not to have seen puffins, but at least we did see gulls, guillemots, and eiders. Also, our cruise featured a trip into a cave where our captain played the saxophone to demonstrate the cave’s acoustical properties.

We walked around the town a little and had lunch a neat little coffee shop called Vinaminni Kaffihus, which is next to Arnor Bakari, and now I feel like I am gaining the ability to read Icelandic. On the ferry back, we were accompanied by I think almost the entire town. They were going to support the town’s school’s handball team which was evidently playing in the national championships or something like that. The entire ferry was decked out in support of the team, and there were eight buses waiting for the them on the mainland. We briefly discussed that since the entire town seemed to have left the island, that we could invade and take possession of the island like modern day pirates. However, we had no idea what to do with the island, and Icelanders are so nice, we didn’t want to do that to them. We decided just to go to Reykavik for dinner instead.

Blue Lagoon

Posted on May 14, 2014 by geek

Day 1 in Iceland. I think I got about 20 minutes sleep on the plane. We drove to the western edge of the Reykjanes Peninsula to see the lighthouses in Garður. Then it was on to Iceland’s most visited tourist attraction the Blue Lagoon. Some genius turned what was a pool formed by wastewater from a geothermal power plant into a rather expensive, somewhat posh hot pot to which all tourists flock. It is really cool though. The water color is this gorgeous, cloudy sky blue. Also, they give excellent massages while you lay on a float in the lagoon. When you’ve been on a plane for six hours with no sleep, walking around a wonderfully heated pool and then getting a massage is quite frankly, a great cure for your exhaustion. Walking around the lagoon is great exfoliation for your feet, and they have buckets of silica from the lagoon to rub on your face for a facial. From a geology standpoint, the pool is really neat because you can walk through micro heat spots, not to mention to entire heated by geothermal heat thing. In some areas the pool is warm and in some areas, the pool is hot. The lagoon was also a great place for me to play with my new GoPro camera, which can be used underwater.

The area around the lagoon is bizarrely pretty. It is dark craggily, sharp volcanic rock that is covered with this lush, soft in appearance, green plant. I am guess the green is actually lichen or a moss, but I need someone to educate me on what it actually it.

Vanity Countertop

Posted on April 17, 2014 by geek

One nice thing about buying a stone slab for your countertop, is that if you have to buy the whole slab, you can request to view and alter the layout of the slab cut out. I found a gorgeous sky blue piece of marble with fluorite crystals in it. Fluorite is my favorite mineral, and the blue goes wonderfully with my green marble tile that will be used as the backsplash. The slab was meant to be mine, and I can never move from my house now. It has now been installed in my bathroom, so this weekend, I will be tiling the backsplash.

Luray Caverns

Posted on August 3, 2013 by geek

Unlike Skyline Caverns, which I visited yesterday, Luray Caverns let visitors take self guided tours through the caverns. This was very nice, as there were employees along the way to ask questions of if you had one, but I didn’t have to listen to a guide telling me what the various formations look like. Luray Caverns has fantastic stalactite, stalagmite, and column formations. It has a couple of small ponds that create perfect mirrors for the formations above, and it is absolutely beautiful and amazing to view. Luray Caverns also has the Stalacpipe Organ, which plays music by hammering stalactites instead of using pipes. It is rather interesting to hear.

Skyline Caverns

I visited Skyline Caverns today in Front Royal, Virginia. I have decided that caverns and other attractions that have some science involved need to have two different tours: one for people interested in the science, such as the geology of cave formation, and others who just want to see the pretty stuff and be told that a particular formation looks like Snoopy. Skyline Caverns has some nice formations and some neat underground rivers and lakes, The lakes are really neat to see because the water is completely still and forms a mirror reflecting all the formations above it. The best part of the tour of Skyline Caverns was the anthodites, which are absolutely beautiful six-sided calcite crystals. According to the tour guide, their existence was first discovered in Skyline Caverns by Walter Amos, the geologist who discovered the caverns.
