I'm fairly certain it's Dryas integrifolia, the entire leaf mountain avens. Mainly due to the fact it has more than 8 petals, which is uncommon in D. alaskensis and D. octopetela. The petals also look more lanceolate than round. Although the leaves are slightly dentate, which would be uncommon with integrifolia, but not unheard of. Dryas can be really difficult to distinguish in the field, and they are thought to hybridize. My next bet would be on D. alaskensis.

Valentine's Day 2023 - Definitely one of the best aurora displays I've seen, although we had a few great ones this year! Still about 56 more days before it starts getting dark enough to see them in Fairbanks, Alaska. https://photos.lwpetersen.com/Galleries/Alaska-Photos/Aurora-Borealis/

@337guanacos Thanks!

Intro to the broad range of topics to be covered in my Physics of Photography Series - light and electromagnetic waves, the camera obscura, image formation, aberrations, geometrical optics, the physics of exposure, and more!

I'm very excited that after a long delay, this series is finally gaining feet. The next article will cover the many ways in which photography is used in various scientific fields.

Physics & Photography Entwined - Lee Petersen

Unravel the intricate science behind the art of photography in this introductory piece, 'Physics & Photography Entwined.' Discover the basic principles that govern light capture and exposure, setting the stage for a deeper exploration into the fascinating interplay between physics and photography.

Late spring aurora from the Granite Tors Trail near Fairbanks, Alaska. It's only two days until the solstice and about 60 days before it gets dark enough in the Alaska interior to see the northern lights again. I miss our winter night skies, but our spring/summer season is going way too fast!

The Physics of Photography: An Integrated Approach - Lee Petersen

The Physics of Photography: An Integrated Approach is an introduction to the series and my philosophy behind it, how physics and photography inform each other.

A fresh dusting of snow reveals the wall of a crevasse on the Gulkana Glacier in the Eastern Alaska Range. The waterfall into the glacier makes this place feel surreal.

Here's my hiking guide to the area: https://www.lwpetersen.com/alaska-guide/gulkana-glacier-hike/

Gulkana Glacier Hike - Guide to Hiking Alaska's Trails and Backcountry

The Gulkana Glacier area has much to offer, including day-hiking, backpacking or mountaineering expeditions, or just a roadside view of the glacier.
