Welcome To My 2021 Field Office

This is my summer receptionist… a Yellowstone 2020 wolf pup of the Junction Butte pack that roams mainly in the Lamar Valley of northern Yellowstone National Park.

My geological field work lately has taken me to several areas of western Montana, so I thought I’d do a visual collage of a few of the landscapes where I’ve been working. To start with, I’ve been spending time flying drones over Tertiary exposures in southwestern Montana, Great fun and good insight into Tertiary geology. Many of my flights are focused on Eocene strata at Pipestone Springs. Along with 3 co-authors (Don Lofgren, Stephen Hasiotis, and Bill McIntosh), we have a paper on Pipestone chronostratigraphy, trace fossils, and depositional environments that is now in review. Below are a couple of drone photos from Pipestone Springs.

Pipestone Springs Eocene strata with the basal lapilli tuff (37.5 million years in age) and the upper trace fossil bed (36 million years in age) indicated. Note the person standing on the surface of the upper trace fossil bed.
A somewhat closer drone view of the upper trace fossil bed with me as pilot standing off to the right side of the photo. My drone landing pad is my friend’s political campaign sign!

My travels through a part of northwestern Montana last week put me in a very different geologic setting from southwestern Montana. Proterozoic rocks are the mainstay in this area, and they make for some spectacular landscapes. So spectacular in fact, that I’ll just do a barrage of photos from the east side of Glacier National Park…

Chief Mountain, located a few miles north of Babb, Montana, is the iconic geologic view of major thrust fault where Proterozoic rocks (Chief Mountain rocks) are pushed over Cretaceous strata (green area of this photo).
No matter how much has changed in this past year because of the pandemic, it is just astounding to me to see a sign that says the Canadian border crossing is closed. It was a heavy mix of emotions being out in the early morning to view Chief Mountain, but then to see this sign and know that we’re still all in this even a year out. Whew…
Of course, no visit to Many Glacier is complete without marveling at Grinnell Point.
One of the positive aspects of getting up very early on a spring day is the sun rise near the Many Glacier Lodge. It didn’t last long as rain clouds pushed in but what a view for a time!
And another plus to being up early in the Many Glacier area is to watch a black bear amble down the road.
Coming back south, down the Front Range of the Rockies, we got out from under the rain clouds. Once again, geologically, the rocks that comprise Dancing Lady Mountain have been thrust over younger, Cretaceous strata (basically the area in green on the photo).

In summary, this is just a quick view of a couple western Montana areas where I’ve been recently. I have to say that I’m really looking forward to more amazing places to work this field season. I may swap out my office receptionist, though.
