...E. P. Henderson; Stuart H. Perry Abstract This iron meteorite was found 6 miles northwest of Hugo, Oklahoma, and was first described by E. C. Wood and C. A. Merrith. 1 It was correctly identified as belonging to the ataxite group with an unusually high schreibersite content. The U. S. National...

...F. C. Wood; C. A. Merritt Abstract On March 14, 1938, Mr. T. J. Stockton of Soper, Oklahoma, forwarded. a specimen to the oklahoma Geological Survey with the request that it be identified. He had picked up this pecuriar material while working on a farm about six miles northwest of Hugo, oklahoma...

... ( Stewart 2002 ). However, the discovery of shocked mineral grains ( Amor et al. 2008 ; Reddy et al. 2015 ) proves that it is the product of a kilometre-scale meteorite impact. The near continuity of the Stac Fada Member outcrop was interpreted as evidence of relative proximity to the impact crater...
