This site has much in common with LAn-9 and LAn-10. The sloping knoll on which the site is situated is part of the ridge that forms the north bank of the intermittent creek. The leeched, indurated soil is hardly recognizable as occupational deposit, but the fact that it forms a site is obvious from its slightly darker coloring and the scattered surface artifacts and reject material. These are thinly strewn over an area of 200 feet by 100 feet, and are found to a depth of 2 feet in the bank resulting from a road cut at the base of the site. The 10 single-edged planes that come from the surface range from large to small, 9 of which are basalt and 1 a pink mudstone. A single massive double-ended plane of basalt is much battered on its worked edges, which are flaked back on their upper side. Battering is also in evidence along the flaked edge of 4 bifacial choppers, 3 of which are basalt and 1 quartzite. Out of 4 basalt flake scrapers, one has been much used; and of 4 core hammerstones, 2 are basalt, 1 is quartzite, and 1 is mudstone. Manos were represented by 3 bifacial types, the grinding surfaces of 2 being parallel, and 1 meeting at an angle to effect a wedge-shaped cross section. All are well-shouldered, 1 displaying a pecked depression on a single wear surface; 2 are of sandstone, 1 of which is carbonized; and the third is of an igneous rock. Again, on all the basalt specimens the patination is very marked. _LAn-12._--The largest site yet found in the canyon is on the property of Mr. Miller on the road to the Trippet Ranch, .25 of a mile southeast of the Tank Site across an intermittent creek. It was noted that in the creek bed, just downstream from the Miller residence, pools of water, which, according to Mr. Trujillo were spring fed, an exceptionally dry summer season. The site extends from the ridge where the house is located into the knoll west of the orchard, covering an area of 400 by 300 feet to a depth of at least 30 inches. Artifacts are plentiful on the ploughed and cultivated surface, and the highly indurated mound soil is dark and clayey. Where the deposit has been cut by recent developments, little worked stone is found in the banks; and a 5-foot square pit netted only one fragment of a ground slate pendant, though the deposit extended below the 30 inches to which the excavation proceeded. From the walls of the pit it could be noted that some soil profile had already developed.
