Re: [FRIAM] "Weather line" on 14
As I think I remember it, I think the opening scenes to Tom Hanks "News of the World" were shot in that vicinity... minor aside is that the "wagon trail" he was on looked like a 2 track modern-vehicle road... wear patterns/stance appropriate to a pickup truck not a 19 century wagon trail.

Here’s a detailed interpretation of its formation based on the description provided: 1. **Composition Analysis**: The Galisteo Dike consists of micro-monzonite, a fine-grained igneous rock. It contains a mixture of minerals including plagioclase, potassium feldspar, titan-augite, titaniferous biotite, apatite, and opaque grains in a glass groundmass. This mineral composition suggests that the dike formed from magma that cooled relatively quickly, preventing the formation of large crystals. 2. **Physical Description**: The dike appears as a dark gray, fine-grained rock with a salt and pepper texture. It weathers to dark brown or grayish brown and forms a wall-like rampart. This implies that the dike is resistant to weathering and erosion, standing out in the landscape as a prominent feature. 3. **Structural Features**: The dike is described as comprising many right echelon overlapping segments varying in length from 200 to 1200 feet and up to 18 feet thick. This pattern of overlapping segments indicates that the magma was injected into pre-existing fractures in the surrounding rock, likely under significant pressure, causing the fractures to open and propagate in an en echelon pattern. 4. **Geological Age**: The dike is dated to 26.55 million years ago, placing its formation in the Oligocene epoch. This was a time of significant tectonic activity in many parts of the world, often associated with volcanic and plutonic intrusions. ### Formation Process 1. **Magma Intrusion**: The formation of the Galisteo Dike began with the intrusion of magma into fractures in the Earth's crust. The magma, originating from deeper within the mantle, was rich in the minerals described and had a high temperature, allowing it to flow and penetrate the fractures. 2. **Cooling and Crystallization**: As the magma moved upward through the fractures, it began to cool and solidify. The rapid cooling near the surface resulted in the fine-grained texture of the rock, with minerals crystallizing quickly in the groundmass of glass. 3. **Fracture Propagation**: The injection of magma caused the fractures to propagate, leading to the characteristic right echelon overlapping segments. This suggests that the fractures did not open uniformly but rather stepped along the strike, with each segment forming as a discrete intrusion event. 4. **Weathering and Erosion**: Over millions of years, the surrounding rock may have eroded away, leaving the more resistant dike exposed as a wall-like structure. The weathering of the dike itself results in the observed dark brown or grayish brown coloration. In summary, the Galisteo Dike was formed by the intrusion of magma into fractures in the crust, followed by rapid cooling and crystallization, resulting in a fine-grained igneous rock with distinct mineral composition and structural features indicative of significant volcanic activity during the Oligocene epoch.

Re: [FRIAM] "Weather line" on 14
Dear Stephen, Thank you for prompting me to respond to this inquiry. I was having some trouble getting the image to behave on my computer, and so was reluctant to wade in. Indeed, just as nature abhors vacuums, she abhors straight lines, and so any line as straight as this one requires a special explanation. To me, that the line points southwestward toward the radar site NW of ABQ suggests a radar artifact, perhaps the shadow or some distant hill. As we watched the animated radar image, we could see a persistent weakness in the radar echo along that line, even as the clouds crossed it. Speaking of abhorrent straight lines, during our conversation with Frank, we spent quite a lot of time discussing another line, a berm of sand that runs across the Galisteo Basin in roughly the same orientation, perhaps 50' high?. I had noticed this feature on topo maps and always assumed it was an old railway embankment. Frank, who knows the area well, thought that idea was absurd. So, we were left with the puzzle of a highly linear geological formation several miles long. Could it be that this geological straight line accounts for the straight line cloud formation that Mr. Kadlubek sees? As the dry line breaks down in anticipation of the SW Monsoon, moist air does indeed move northward, following the river valleys up from TX. AT some point, it will be raised enough that its moisture is condensed leading to the release of latent heat and the further development of clouds. If the structure that raises it is a straight line, then the clouds themselves will be arranged in a straight line. We can see this effect often along linear coast lines as a sea breeze front topped by (usually) fair weather cumulus. However, given all the dramatic topography in the area, it's hard for me to imagine that this low lying feature would be determining very often. I, too, live for the weather. I don't live for Face Book, however. So if you have any way to put in touch with Mr. Kadlubek, he and I could perhaps have coffee when I get back to Santa Fe in the fall.
