JOE WRIGHT MOUNTAIN. 



Independence County, Arkansas. 



Here also Batesville, Elmo, and Independence County. 



Latitude 35° 49' N., longitude 91° 37' W. 



Iron. Medium octahedrite (Om) of Brezina. 



Found 1884; described 1886. 



Weight, 42.5 kgs. (94 lbs). 



This meteorite was described by Hidden ' as follows : 



This meteor was found about the last of June, 1884, by George W. Price, on what is known as the Joe Wright 

 Mountain, a small eminence about 7 miles east of Batesville, Independence County, Arkansas. The soil there was 

 cut into deep gullies, which farther down the mountain side converged into one, at which point this meteorite was 

 found. * * * 



The weight of the mass was 94 pounds. It was 17 inches long and 8 inches thick. Its surface was pitted with 

 ovoid depressions of various sizes, lying with their longer axes in nearly the same general direction. 



The exterior was almost black in color and looked blistered. No rust or alteration from oxidation was noticed on 

 any part, indicating that the mass had not lain long upon the earth. * * * A large hole near the edge measured 

 five-eighths of an inch at its smallest part, was 1.75 inches long, and was cone-shaped from both sides. 



Etching showed Widmannstatten figures well developed. Troilite having a bronze color and luster occurs as thin 

 seams and veins on the polished face and extends far into the mass. Schreibersite as rather large bright points was 

 also noticed.

Other elements were not looked for. 

 Brezina 2 remarked regarding the form of the mass as follows : 



An unusual interest attaches to the iron from Joe Wright Mountain on account of its natural perforation, due to 

 its great richness in troilite. 



Joe Wright and Glorieta stand in a certain opposition, as they illustrate two very different methods of the rending 

 of meteoric iron; the rending, in consequence of perforation, widening the holes until they form a ring, and finally 

 bursting the ring, of which method Joe Wright shows the primary stage; and, on the other hand, the rending in con- 

 sequence of the formation of fractures of which the Glorieta iron shows the final stage. 



Cohen 3 gave an account of an investigation of this iron, as follows : 



About 32 grams of this iron were investigated. Etched faces show hatched kamacite, distinct teenite border, and 

 plessite of separate formation. One part contains delicate combs, another is of granular structure, and then either 

 uniformly dark gray or rich in minute shining points. Especially characteristic are little plates above 1 mm. in thick- 

 ness and up to 35 mm. in length, which seem to stand perpendicularly to one another and qualitatively appear to be 

 schreibersite.
