A look at serpentinization

Joaquin Miller Park contains excellent examples of serpentinite. This large boulder, placed by the park entrance, is a textbook example of how this rock type forms. (Click the photo for a 1000-pixel version.) Serpentine rock starts out as peridotite (“per-RID-a-tight”), a very important rock type that is rarely seen because it composes most of the

Another pretty cool looking oyster that I found in the Texas creek I was exploring is Peilinia quadriplicata (also called Ostrea quadriplicata). This species is very easy to ID based on the look of the shell. I only found a left valve but it has the typical splayed look to it, kind of like a duck foot. While the shell started out with a relatively smooth margin, as the animal grew older it started to have some distinct "points" with flat, straight areas of margin between them. Overall the shell [...]

Mapbox updated their mapstyles

Today I received the newsletter from Mapbox with interesting screenshots of their new mapstyles. The company convinced many users with nice basemap styles already in the past. Now they updated their background mapstyles for webmap usage. Just have a look: All pictures are from Mapbox. In my opinion the new styles fits good for modern map applications. If you’re interested in other background maps, check out this article – Map Compare. If you’re interested in getting more [...]

There are Islands in the Desert: A Look at Ash Meadows National Wildlife Refuge

There are islands in the desert. One might argue that islands are supposed to be surrounded by water, and water is in short supply in the driest corner of North America's Basin and Range province. But islands can take many forms, and in this region there are extremely high mountains and deep fault valleys that cross so many life zones that the "island" can be defined as an isolated

Okay I have to confess: I was invited to the beer friday at ally HQ in Berlin Mitte. I liked what I saw there and I also had a nice chat with Uli whom I met during the geo Berlin Meetup for the first time. So let’s have a look at what ally is about. Ally is a Berlin base startup which started with an app some years ago under the name allryder. Ally itself is “part of” the Door2Door GmbH. You’ll find some other buzz-names like waymate and time2gate in the tag cloud of the [...]

We depart the Little Colorado in mid-afternoon of an early May day, continuing on Day Four of our excellent Colorado River rafting adventure. The sky that earlier teased us with a warm patchy blue has turned again to cold gray. The sun is a vague, hazy blob behind the thickening clouds. We huddle beneath blue tarps in a futile attempt to stay warm and dry. The Tapeats Sandstone is about to disappear up, up, and away from the water’s edge.The [...]

The geology east of Harpers Ferry, West Virginia, is cool. It’s Blue Ridge rocks, from basement to the cover sequence, tilted to the west and broken and repeated by the Short Hill Fault. Here’s a look at a detail of the Geology of the Harpers Ferry quadrangle by Southworth and Brezinski (1996). So there’s a fault! Good – but the title of this post isn’t “Friday fault” – Where’s the
