flows NE to Kateel River, 71 mi. SW of Roundabout Mtn., Nulato Hills. 26 miles long.
Name published on a manuscript map dated 1906. This is probably a form of a Koyukuk Indian name unless a typographical error changed in "r" to a "v," in which case it may refer to a primative ore mill often spelled "arrestra," "arestra," and "arrastra."
