The Dog Town Mine Tertiary fossil vertebrate locality is nestled on private property within the southern extent of the Elkhorn Mountains, southwestern Montana. The locality is about 20 miles southwest of Townsend, Montana, where Mesozoic and Paleozoic carbonate, quartzite, and red-colored mudstone, siltstone, and sandstone rocks underlie Eocene (Chadronian) strata. These unconformable Eocene strata contain…
Earl Douglass and the Tertiary Geology of Southwest Montana’s Madison Bluffs
Most vertebrate paleontologists probably think of the spectacular dinosaur finds near Jensen, Utah, when the name Earl Douglass is mentioned. Douglass’s discovery of a partial Apatosaurus near Jensen in 1909 did spark the beginning of his long career with finding more dinosaur material in what we now know as Dinosaur National Monument. But Douglass began his quest for…
Iceberg Lake Glacier, Glacier National Park – Hiking Through A Changing Landscape
Iceberg Lake is situated in the Many Glacier area of Glacier National Park. The hike is about a 10 mile round trip and gains about 1275 feet in elevation. The trail winds through prime grizzly bear habitat, so be sure to hike with a group, make lots of noise, and carry bear spray. It would…
A Different Look At The Burgess Shale – The Stanley Glacier Burgess Shale Hike, Kootenay National Park, British Columbia, Canada
The Middle Cambrian Burgess Shale and its contained fossils are legendary to earth scientists. These fossils are by far the best record of Cambrian animal fossils. The importance of the Burgess Shale fossils is also linked to their excellent preservation. The fossils include many soft bodied animals in addition to those with hard parts –…
The Gravelly Range, Southwestern Montana: High Elevation Tertiary Rocks
The Gravelly Range is located in southwest Montana, about 10 miles southwest of Ennis, Montana. Much of the range is covered by the Beaverhead-Deerlodge National Forest. The Axolotl Lakes Wilderness Study Area, managed by the Bureau of Land Management, is in the northern part of the Gravelly Range. Our field group was interested in looking…

Geological Travels In Cuba
If you’ve ever thought about Cuban geology, now may be the time to get serious about actually going to Cuba and looking at it. As a U.S. citizen, it’s been extremely difficult to legally go to Cuba. I went there in March of 2013 as part of an Association for Women Geoscientists’s geological field trip…
IPCC Hones Its Language on Climate Change
Yesterday the Intergovernmental Panel on Climate Change (IPCC) released its latest Synthesis Report (SYR5) – a summary of the IPCC’s Fifth Assessment Report (AR5) on the state of knowledge on climate change. The big news with the SYR5’s release is the change in language used within the report – words like “unequivocable” and “clear” now…

Notes From the Field – The Rest of the 2014 AWG Geology Field Trip
The 2014 AWG Canadian Rockies Geology Field Trip did actually end last Sunday (9/7) and we did indeed make it back to Calgary largely unscathed. As many of you probably know, when lodging amenities state that WiFi is included, it most likely means that one can check email – not post blogs with photos of…
Notes From The Field – Revelstoke to the Okanagan
Finally we had a mostly sunny day! We began the day with a tour of the Revelstoke Dam. This dam was one of the last Canadian dams built within the Columbia River watershed. The dam area is really interesting because just across the highway from the dam is the Columbia River Fault zone – a…
Notes From The Field – Lake Louise and Moraine Lake
I’m backtracking somewhat here by posting on our trips to both Lake Louise and Moraine Lake. Both are so gorgeous that I didn’t want to exclude them from the postings, but my SD card with their photos was not accessible when I did the initial postings. Suffice it to say that hikes and canoeing in…
Notes From The Field – Field, B.C. to Revelstoke, B.C.
The AWG field trip continued along the Trans-Canadian Highway 1 from Field, B.C. to Revelstoke, B.C. – again in the rain. But at least the rain stopped several times for us to have fun at our trip stops. We followed the Kicking Horse River to its junction with the mighty Columbia River at Golden, B.C…..
Notes From The Field – The Burgess Shale Hike
The hike to the famous Walcott Quarry in the Burgess Shale near Field, British Columbia, was one of my highlights of the AWG field trip.The hike was long and seemed to go on forever – especially the climb up to the quarry. It was in total about 11 km into the quarry and then 11…
Notes From The Field – Icefields Parkway
After more rain and no wifi, we’re finally in Revelstoke, British Columbia where we still have rain, but finally have some wifi. We had a great trip from Lake Louise (I will post a few photos of scenes from Lake Louise later as my camera flash card for that part of the trip is still…
