Meanwhile in BC:
February means #OpusDailyPractice, our local fine art supply store organizing prompts & meetup (opusartsupplies.com/odp)

I’m far from home, but I have a sketchpad & pens and I’m still trying to be less shy about my art, so let’s do this. 💚 Border & Riley #234 pad, Pigma micron pens in a variety of sizes, and a collection of grey, blue, purple, & red Copic markers
1. Kathmandu, Nepal.
I’m working with pen-only (#inktober redux?) & not fussing over scale as all my #geology #sciart has absurd vertical exaggeration.

...but I couldn’t accept the combo of a very small valley & the metamorphic pattern feeling more “Christmas” than “rock.” Partially-patterned ink drawingFully-patterned ink drawingIncomplete first draft, complete second draft of a detailed geologic cross section of Kathmandu valley in Nepal
2. Tehran, Iran
This feels like approximately a zillion variations of sedimentary textures (alluvial beds).

I had fun playing with miniscule variations in pen widths (💚 those microns!) for today’s #OpusDailyPractice #geology #sciart Ink drawing of a geologic cross section

#Inktober index card 1: Relative dating is a snippet of simple magic. As soon as you stop to think logically, entire landscapes unravel in eagerness to tell you their story. #sciart #geology #teaching
#Inktober index card 2: #DonnaStrickland is the 3rd woman to EVER win the #NobelPrize in #Physics for her work on chirped pulse amplification, an engineering #optics technique to create short, intense laser bursts with broad industrial & medical applications. #sciart #cansci
#Inktober index card 3: I’m #TeamIce for #MinCup2018, infatuated with this simple & elegant mineral.

Here’s my interpretation of ice from chemical composition to melt molecules to crystal hexagons. I couldn’t find my blue pens for sketching the #thinsection. Shush.

Vote ice!
