VICINITY OF OMAHA, NEBRASKA
To the southward of Omaha are many lodge sites of varying depths and diameters. The deepest one reported had a depth of 9 feet below the surrounding surface, and at the bottom of this was a pit (or "cache," as they are locally known) with an additional depth of 4 feet, or 13 feet of excavation in all. This was near the so-called "cannibal house," where 14 human frontal bones were found under conditions which indicate they had belonged to individuals who were eaten by other inmates of the lodge.
A short distance from these sites, across a ravine, is a bare, narrow ridge, very steep on each side, so that erosion would readily act. On the sloping summit of this are three small mounds which cover communal burials. From one of these, the one farthest from the summit of the hill, more than 80 skulls were taken and boys in the neighborhood have since taken many more. They are all of the ordinary Indian type, and can not have been buried more than a few generations ago; but this fact has not prevented an age of "twenty thousand years" being assigned to them. There is absolutely no reason for fixing this or any other date. There is nothing whatever to indicate the age, but 200 years would probably not be far from the mark, because erosion has been slight since the mounds were piled up.
LONG'S HILL
This ridge has attained some notoriety as the site of Gilder's discovery of the "Nebraska Man." The claim is made that human bones were found at a depth of 14 feet in absolutely undisturbed loess. The hill is a narrow ridge, facing the river on one side and a deep ravine on the other. It is somewhat winding in its course and is connected with the more level land in the rear at about half a mile from its end. A wagon road up the point, from the river bottom to the hilltop, shows undisturbed loess the entire distance. There is no possibility of accumulation by wash or in any other manner except decaying vegetation on any part of this ridge.
Along the crest are several small mounds. Some of these, as shown by excavation, cover graves, and the presumption is that all of them mark burial places.
It is needless to make any résumé of Gilder's report, as it is so well known, further than to say that he found burials and fragmentary human bones at various levels from 2½ to 14 feet. At 4½ feet were burned bones lying upon burned earth and mingled with it. This layer, burned hard as a brick, served to prevent water from penetrating the earth immediately below; and it is in this earth that the deepest remains were found.
There are three ways, and only three, in which they could get there:
1. They were washed in when the loess was deposited, as claimed by the discoverers and by some of the Nebraska geologists.
