Finally finished the Geologic Mapping binder!!! Also reorganised a bunch of my stationary for the new year!

Didn’t feel very motivated to do work today but still managed to do some GeoMapping stuff for Scioly.

Currently playing:

Another cross section completed

Working on some cross sections is geologic mapping today. So tedious

“Global Positioning System”           Today, my partner and I decided to go inside the volcanic vents and fissures; some portions required rock-climbing, crawling, and shimming. It was about 30 degrees cooler down there in some parts! It was honestly my favorite part of this trip so far. I felt like Indiana Jones! more pictures to come.          Now back to mapping. Generally, mapping would be annoyingly tedious using GPS; a good mapper  relies on reading the land and positioning himself using a topographic map. A subtle gully or ridge can be located using notable landmarks in the area. HOWEVER, for this exercise, we had some tricky terrain; we had to map a volcano in Mono Basin, including the fissures, carbonate layers, and some bedding that had little topographic indicators. In the words of Dr. Hausback, “you could map a gnat’s ass with this thing”. Indeed, it was precise.

“The Write-Up Day”        Whenever we’re done with a mapping project, we have a day at the facility to finish our final products. The purpose of creating a geologic map isn’t to make a piece of art (although it is in a way), it’s collecting data in the field and manifesting it visually. Wherever different beds of rock lie next to each other tells a story! However steeply dipping the beds are tells a story! Folds, faults, landslides, etc.          This data is then interpreted into a chronological history (deposition, uplift, fracturing, erosion, etc.). Write-up day is the day where we can look at our map, and decide what the heck we just looked at for the previous week in the field. We often have our textbooks handy, and any previous articles written about the area in order for our maps to come to life.

hey! i'm doing scioly dynamic planet at southern california competition next week and i was wondering if you had study tips for this particular topic? THANK YOU AND CONGRATS ON SIXTH <3

2. (omg wait, i’m doing geomapping as well that’s so weird) i would also appreciate study tips for geomapping because this is literally a yolo topic for me (i’m also an infj! coincidences haha)

i hope you don’t mind me answering these publicly, i don’t think links work very well over private answer :U

but ahhh thank you so much ;u; <33 and hmmm well for me, i did most of my studying from the two slideshows that are linked on the national site under dynamic planet (here it’ll be the ‘Glacial Erosion Slideshow’ links), they’re easy to understand and actually cover a lot of what i saw on my tests (difference glacier types, landforms made by them, etc). however all of the other links on there are pretty helpful as well! another piece of advice i would give is to know not only what landform is what, but to know what category the landforms fall under; depositional (like an esker or moraine), erosional (cirque or arete), glacial lakes and ponds (kettle lake, tarn, etc), or ice features (i didn’t see any of these on our test, but i believe valley glaciers and icefalls are examples). also, STUDY THOSE TOPO MAPS!! my partner and i had to read three on our test and discern how a glacier moved through the land/what features it left behind, and it was no walk in the park. i can almost guarantee you’ll see some of those if it’s a state/regional competition you’re competing in.

as for geomapping, i’m not sure what advice i can give for this one. :c there aren’t really any free resources on the national site yet because it’s a new event (my partner and i did the trial run of this event at states last year and it was waaaay different from how it is now, so i’m still adjusting to it as well), but i got a resource cd from my coach with a ton of helpful documents on it! i don’t know if you were distributed the same thing or not… O: there may be a way for me to transfer the .pdf files of them to you though, i could try putting them into a .zip file. but mostly it’s knowing a lot about the different kinds of fault structures in the earth (faults, strikes, folds, etc), as well as being able to look at a map of rock layers and ordering it from oldest to youngest. the law of superposition is your friend! also on one test we were required to draw a contour/elevation map, which i didn’t know how to do at the time, but since then i’ve found this handy guide that makes it easy to understand! (here!) topo maps are also used in this event, so definitely attack those and learn how to read/use them. c: i hope at least a little of this proves helpful to you, and good luck at your competition!! *u*

also dang, that’s a lot of coincidences right there O: but that’s awesome, not many people are infjs! we’re a very rare type apparently.
