NO. 10 SMITHSOXIAN EXPLORATIONS. I923 "/"J 



As opportunity permitted during the exploration of Pueblo Bonito, 

 attention was also directed to a neighboring ruin, Pueblo del Arroyo. 

 Excavations in this latter village were under the immediate super- 

 vision of Mr. Judd's chief assistant, Mr. Karl Ruppert, of the Uni- 

 versity of Arizona State ]\Iuseum. 



This first season's exploration in Pueblo del Arroyo resulted in the 

 complete excavation of one kiva and 20 living rooms. One of the 

 latter is 58 feet long but its original length, before certain partitions 

 were constructed, had been almost twice as great. In addition to the 

 excavations within the walls of Pueblo del Arroyo itself an accumula- 

 tion of debris was removed from the south and west sides of the ruin. 

 In this debris nine small rooms were unexpectedly discovered — rooms 

 which formed no part of the original ground plan of the pueblo. 



Several unique specimens of pottery were recovered during the 

 initial explorations in Pueblo del Arroyo and the success of this past 

 season increases the belief that this particular ruin possesses much that 

 will add to the scientific importance of current studies in Pueblo 

 Bonito. Pueblo del Arroyo appears to have been designed and erected 

 as a unit ; it lacks the many intricate problems created by successive 

 waves of immigration so evident in Pueblo Bonito. The 1923 explora- 

 tions in Pueblo Bonito and Pueblo del Arroyo were conducted at a 

 cost of more than $18,700. The success with which this expedition has 

 been rewarded during the past three years warrants the belief that 

 the National Geographic Society will continue its explorations during 

 the next two years at an estimated cost of $15,000 annually. This is 

 in conformity with the Society's program as adopted l)y its research 

 committee in 1921. 



EXPLORATIONS IN SAN JUAN COUNTY, I'TAH 



Bordering the Rio Colorado in Utah are vast areas which, owing 

 chiefly to their inaccessibility and barrenness, have thus far escaped 

 thorough examination by men of science. Certain portions of these 

 areas, indeed, have never been visited by white men. To investigate 

 one such district, that lying immediately east of the Colorado and north 

 of the San Juan rivers, and to determine whether further, more 

 detailed researches therein were desirable, the National Geographic 

 Society, in cooperation with the Smithsonian Institution, organized a 

 small reconnaissance party for explorations during the months of 

 October and November; Mr. Neil M. Judd. curator of American 

 Archeology, United States National Museum, was designated leader 

 of this expedition.
