What Is the Hidden Story of the Strange Indian Shell Mounds?

THE Indian shell-heaps, or mounds, of California have ever been a source of wonder. They are to be found from one end of the State to the other, wherever a beach, bay or estuary gave the savages an opportunity to gather the succulent bivalve. The origin of these mounds is shrouded in mystery, and, strange as it may seem, little effort-has ever been made to fathom it. Paul Schumacher of the Smithsonian Institution published a brief account of his investigations of a mound in San Luis Obispo county in 1874, since which time, no other article worthy of note dealing with the subject has appeared. The University of California has in preparation a pamphlet on the result of the investigations of the shell mounds of Berkeley and Shell Mound.

Marin county is dotted with these heaps. They are to be found near Sausalito, Mill Valley, Corte Madera, Ross, San Rafael and Novato. Varying slightly in size, they are identical in form and structural elements. For example, the mound near Mill Valley is oblong, being approximately 400 feet long by 300 feet wide, and about 20 feet in height. One mound near Alto is somewhat longer and not quite so high. This one has a wagon road cut transversely through its middle.

Concerning the purposes of these mounds, the following questions naturally arise: Were they of a ceremonial character? Were they burial mounds? Or, were they simply the result of casting offal and rubbish in the same place for ages? In considering these questions it is necessary to give a description of the materials found in the mounds.

The mounds are composed almost entirely of shells, Clam shells, mussel shells and oyster shells, with barnacles, here and there, make up most of the body. With few exceptions, all of the shells appear to have been opened. Interspersed throughout are the bones of human beings, animals, birds and fish. At the very bottom, the shells are thoroughly disintegrated-mutely testifying to their great antiquity. As the top is approached, the shells become gradually more firm and sound, until, at the very surface, they are almost perfect.

The creation of these mounds must have required generations, if not centuries. And, whatever their purpose, they were evidently the result of seasonal or temporary operations, for layers of earth recur at short intervals in the strata of shells. This would indicate that the Indians dwelt in the neighborhood of the mounds at certain seasons of the year only, probably during the winter time when food, other than shellfish, was scarce. During their residence elsewhere the winds would drift the sand and earth over the shells.

Why these mounds were constructed is a question difficult to answer. Schumacher believes that they are nothing more than heaps of kitchen offal. But, if such be the case, why are the mounds so large, and why are human remains found in them? His contention is supported by the fact that few arrow-heads, spear-heads, flint knives or others implements are to be found.

Careful examination seems to indicate that these deposits are the result of tribal ceremonial feasts. Were they not the result of concerted tribal action, one would naturally expect to find multitude of small
heaps, and such is not the case. The California Indian was never noted for his sense of neatness, nor for his observance of sanitary rules, and his laziness was such that he would not carry his kitchen refuse very far from his fireside, let alone carrying it to the top of a mound, even to relieve himself of offensive odors.

Examination of a transverse section of one of these mounds discloses well-defined beds of ashes, which are large and from three to twelve inches in depth. Underneath them is usually found a base of burned and smoke-marked stones. This goes to show that the shellfish, animals and birds were cooked, eaten, and their refuse dropped on the spot. The recurrence of the beds of ashes in each stratum of shell shows that the feasts were held whenever the tribe gathered in the vicinity. It is reasonable, then, to suppose that the holding of these feasts on the same spot, year after year, until the surface was raised some fifteen or twenty feet above the level of the earth, could only have been in accordance with some sort of ceremonial observance.

That these mounds were, in any sense, burial mounds, is not to be considered. Why human remains are to be found among the shells and other bones is hard to surmise. The Indians of California venerated their dead, and funeral ceremonies were carefully carried out. They either burned their dead or else carefully buried them. In either case, the personal effects - bow, arrows and ornaments - were laid with the body. None of the human bones found in the shell mounds are charred or marked by fire, hence the mounds could not have been funeral pyres. Those skeletons found are not in regular position, and are sometimes scattered, and no trinkets or implements surround them, showing that they were not carefully or regularly buried. Their presence is an enigma. Are the human remains those of enemies slain in an attack on the rancherias, or are they those of members of the tribes who built the mounds, and who were deemed unworthy of regular burial?. The solution must be left to time.
