Anime everyone ignore this. it's my homework :)

I can't get to email from the lib computer, so I am using the forum for a temp depository of some stuff I looked up

Title: Stratigraphy of the Eocene Willwood, Aycross and Wapiti Formations along the North Fork of the Shoshone River, north- central Wyoming.

Abstract: The Willwood Formation along the North Fork of the Shoshone River forms the base of the Eocene section and was deposited over eroded Cretaceous Cody Shale. On Jim Mountain, it consists of a thin basal wedge of fine lacustrine sediment, followed by some 300 m of fluvial deposits. Fossil mammals indicate that here the Willwood Formation spans from early to middle Eocene (latest Wasatchian to early Bridgerian Land-mammal Age), The Willwood Formation was deposited in a marginal basin whose relationship to the Bighorn Basin proper remains to be clarified. The Aycross Formation, formerly included in the basal part of the Wapiti Formation, overlies the Willwood Formation. This is the most northern exposure of Aycross rocks; an angular unconformity separates these units from the overlying Wapiti Formation. Unconformable contacts at both the base and the top of the Aycross Formation are the consequence of folding, possibly related to the movement of the South Fork thrust and/or the Heart Mountain fault. Fossil mammals indicate a middle Eocene (early to middle Bridgerian) age for the Aycross Formation in the study area and farther to the south. The activity of a composite volcano in Sunlight Basin produced breccias, lavas, and volcaniclastic sediments of the Wapiti Formation, as well as lavas now exposed as the Trout Peak Trachyandesite. Limestone blocks displaced by the Heart Mountain detachment fault on Carter Mountain are overlain by volcaniclastics of early to middle Bridgerian age. Along the North Fork of the Shoshone River the Heart Mountain fault blocks rest on the early-middle Bridgerian Aycross Formation thus providing the first accurate dating (early-middle Bridgerian) for the Heart Mountain fault. -from Author

Title: Paleontology and correlation of Eocene volcanic rocks in the Carter Mountain area, Park County, southeastern Absaroka Range, Wyoming.

Language: English
Abstract: The Wapiti and Aycross formations are lateral and time equivalent units. Use of the name Pitchfork Formation is abandoned. Based on paleomagnetic studies, flows on Ptarmigan and Carter mountains are assigned to the Wapiti Formation (Jim Mountain Member?) and an unnamed sequence rather than to the Trout Peak Trachyandesite. The Blue Point marker overlies the Aycross and Wapiti formations (and the unnamed sequence), and underlies the Tepee Trail and Wiggins formations. The Tepee Trail Formation intertongues with the lower part of the Wiggins Formation in the Greybull Valley area, and is overlain by the Wiggins Formation to the S. The fauna from the Wapiti Formation compares with those of the Bridger 'B.' The faunas from the 'turtle-lake beds' (unnamed sequence) and from the Blue Point marker appear to be transitional between those of the Bridger 'B' and 'C'. Two new species, Pseudotomus sundelli and Hyopsodus tonksi, are described. The Wapiti Formation was probably deposited during normal event 21 of the magnetic anomaly scale. The unnamed sequence and the Blue Point marker may have been deposited during a short reversed episode within normal event 21.-Author

Abstract: Blackstone (1985) published an interpretation of South form detachment fault and related features. His interpretation of the area between Castle and Hardpan transverse faults is identical to mine of 1941. Subsequent detailed mapping has shown that the structure between the transverse faults is more complicated than originally envisioned and resurrected by Blackstone. The present paper describes and discusses geologic features that are the basis for my interpretations; also discussed are differences between my interpretations and those of Blackstone. Most data are shown on the geologic map of the Wapiti Quadrangle (Pierce and Nelson, 1969). Blackstone's 'allochthonous' masses are part of the South Form fault. Occurrences of Sundance Formation, which he interpreted as the upper plate of his 'North Fork fault', are related to Heart Mountain fault. Volcaniclastic rocks south of Jim Mountain mapped as Aycross Formation by Torres and Gingerich may be Cathedral Cliffs Formation, emplaced by movement of the Heart Mountain fault. - Author

This was a pic posting experiment. it is dead now

I now know what I did not know before!!!

The Paleontology one was interesting...

 

I too improved my knowledge of paleontology.

Anyone wanna see my English paper? LOL that's a joke guys.

~ Lady Aoi: How many days till finals are done?

 

LOL! I just realized I knew most of this already. The Wapiti Indians are one of my faves...

MT, realizing how much of a geek she is...

~The SUPER OTAKU!!!

 

Heh, look at all the interest.. I am surprised really. I figured NW wyoming would be an interesting place to learnmoe about, we have an old cabin up 20 miles to the west of Wapiti, and the landscape is weird, so I looked up some stuff on it for my geology class Coll reading about all these places and mountains I know in stuffy journals. My dad and I climbed Ptarmigan mountain just this summer..



edit.. checking if AOL homepages let you link to pics like them. Sorry about the size, but no one should be coming in here, especially since I am not making a new post to do this
