Cuban Geology – An Updated Resource List

Vinales Valley in Cuba was designated a UNESCO World Heritage Site in 1999.

Within the last few weeks I’ve had several requests for available resources on Cuban geology. The requests, of course, have come from individuals outside of the U.S.A. Guess that they sense opportunities for working with and understanding Cuba’s geology that we are backing away from. In any case, I’ve sent the requests on to Manuel Iturralde-Vinet, the person who has worked and published an immense amount of information regarding Cuba’s geology. Manuel has now sent me back an updated list of resources and said:

You can advertise to all your friends and colleagues that a large
percentage of the geology, geography, paleontology, geophysics and
mining papers are free to be visited at

Glacial Geology Field Tripping in the Northern Yellowstone Area

Living near Yellowstone National Park has its advantages – and the best of these is being easily able to go on field trips to the Park area. A field trip opportunity came up last week when the Rocky Mountain section of the Geological Society of America came to Bozeman, Montana, for its annual meeting. One of the meeting field trips was the “Glacial and Quaternary geology of the northern Yellowstone area, Montana and Wyoming”. The trip was led by Ken Pierce, Joe Licciardi, Teresa Krause, and Cathy Whitlock. Having spent much time in the Yellowstone area, I was ecstatic about going along to find out about recent geological work. I won’t elaborate on the specifics of the trip, but for those interested in more than the photos posted below, the field trip guide is available in The Geological Society of America Field Guide 37, 2014, p. 189-203. It’s worth a read!

A few of the stops on the trip:

Paradise Valley – Chico Moraines and Chico Outwash (45.3402 N, 110.6967 W)

Chico moraine boulders have an average cosmogenic age of 16.1 +- 1.7 10BE ka.

 

A succession of outwash terraces border the melt-water channel which is now the Chico Hot Springs road.

North Gardiner Area – Giant Ripples (45.0551 N, 110.7659 W)

Giant ripples occur on a mid-channel bar a few miles north of Gardiner, Montana.
Cosmogenic ages on the flood deposit boulders of the giant ripples average 13.4 +- 1.2 10Be ka.

Northern Yellowstone NP – Blacktail Deer Plateau (44.9577 N, 110.5652 W)

The Blacktail Plateau is capped by moraines of Deckard Flats age - 14.2 +- 10Be ka.

Northern Yellowstone NP – Phantom Lake Ice-Marginal Channel (44.9554 N, 110.5289 W)

The ice-marginal channel that Phantom Lake lies in was cut into volcanic bedrock during the Pinedale glacial recession. The lake is dammed on its down-stream end by a post-glacial age alluvial fan.

Northern Yellowstone NP – Junction Butte Moraines (44.9128 N, 110.3854 W)

The Junction Butte moraines have an age date of 15.2 +-1.3 10Be ka. Large  boulders of Precambrian crystalline rocks and several ponds typify the morainal surface.
