Here and there, near the base of the ridge from this point easterly for about a mile, were found small pits, such as one shown in Fig. 1, Plate VIII. Apparently, these were rock-slide graves from which the human remains had been removed, either by the Indians in early times or more recently by visitors from the neighboring town of North Yakima. Possibly some of them are old cache holes. One of these graves near the top of a small rock-slide above the flume contained a human skeleton and is shown in Fig. 2, Plate VIII. Below these graves, on the narrow flat between the base of the ridge and the Yakima River at a point about three quarters of a mile below the Upper Gap at the mouth of the Naches River, were discovered a number of small pits each surrounded by a low ridge of earth which were probably the remains of cache holes made by the Indians during the last twenty years. On this flat, close to the river were two pits surrounded by a circular ridge which indicated ancient semi-subterranean house sites, further described on page 51. It is said, that above the flume at a point about a mile and a half below the Upper Gap, rock-slide graves, some of which were marked by pieces of canoes were excavated by school boys. The writer was also informed by small boys that near the top of the ridge immediately above here, they frequently found chipped points for arrows but on examination discovered only chips of stone suitable for such points, the boys either having mistaken the chips for points or having collected so many of the points that they were scarce. On the west side of the Yakima, at the Upper Gap, there is a raised flat top or terrace that overlooks the mouth of the Naches River to the southeast. Here were a number of circles made up of angular rocks. Within each we found the remains of human cremations. Unburned fragments of the bones of several individuals with shell ornaments were often present in a single circle.[17] [17] See p. 142 and Fig. 1, Plate IX.
