Adam-ondi-Ahman, then, or Diahman, as it was familiarly known to the Missouri saints, is located on the north bank of Grand River. It is situated, in fact, in a great bend of the Grand. The river comes sweeping down from the north-west, and here makes a bold curve and runs in a meandering course to the north-east for some two or three miles, when it as suddenly makes another curve and flows again to the south-east. We have already spoken of Grand River as a stream that has worn a deep channel for itself, and left its banks precipitous; but here at Diahman that is only true of the south bank. The stream, as it rushed from the north-west, struck this height of prairie land containing beds of lime-stone, and not being able to cut its way through, it veered off to the north-east, and left that height of land standing like a palisade that rises very abruptly from the stream to a height of from fifty to seventy-five feet; but the summit of these bluffs is the common level of the high, rolling prairie, extending off in the direction of Far West. The bluffs on the north bank recede some distance from the stream, so that the river bottom at this point widens out to a small valley. The bluffs on the north bank of the river are by no means as steep as those on the south, and are covered with a heavier growth of timber. A ridge or spur runs out from the main line of the bluffs into the river bottom some two or three hundred yards, approaching the stream at the point where the curve is made. The termination of the bluff is quite abrupt, and overlooks a considerable portion of the river bottom. On the brow of the bluff stood the old stone altar which the brethren found there. When it was first discovered, according to those who visited it frequently, it was about sixteen feet long, by nine or ten feet wide, having its greatest extent north and south. The height of the altar as the brethren found it, was some two and a half feet at each end but gradually rising higher to the center, which was between four and five feet high--the whole surface being crowing. Such was the altar at Diahman when the brethren found it. Now, however, it is thrown down and nothing but a mound of crumbling stones mixed with soil, and a few boulders, mark the spot which is doubtless rich in historic events. It was here that the patriarchs, associated with Adam and in his company, assembled at this altar to worship their God. Here their evening prayers ascended to heaven in the smoke of the burning sacrifice, and here angels instructed them in heavenly truths--but more of this anon.
