All of the mounds on Dayton's Bluff were destroyed sometime before the mid-1890's.

Lewis p.207:
"[At Dayton's Bluff] there was formerly a group of mounds located between what is now [Mounds Boulevard] and the edge of the bluff, and extending from Euclid to a short distance below McLean street, a distance of a little over five blocks. This group formerly consisted of 32 mounds, but at the time of a personal survey by the author on Nov. 1, 1881, nine of them, principally located near the center of the group [between Cherry and Short streets], had been entirely demolished."

Arzigian p. 471:
"In 1995, the [Office of the State Archaeologist] monitored earthmoving activities for reconstruction of a parking lot built earlier over a number of mounds. The monitoring documented historic fill but no human remains or traces of the mounds".

Mound 1:
Lewis p.320:
"On August 18th, 1882, No. 1, which was 24 feet in and 1 foot in height, was excavated. At the depth of one foot were some pieces of decayed wood resting upon a thin bed of charcoal and ashes. At the depth of two feet three inches were the decayed portions of four skeletons, together with several muscle shells."

Mound 2:
Lewis p.320:
"[August 18th, 1882] In No. 2. which was 22 feet in diameter and 1 foot in height, at the depth of thirteen inches were several short pieces of decayed oak wood, resting upon a thin bed of ashes, and at two and one-half feet were portions of three skeletons. Among the bones were 27 muscle shells, and some small fragments of pottery composed of shell and clay."

Mound 10:
Lewis p.319:
"[On November 1st, 1881] No. 10, which was 20 feet in diameter and one and one-half feet in height, was excavated. At a depth of two feet five inches, and four feet five inches southwest from the center, was a granite boulder, averaging about 20 inches in diameter, on the top of which was a small vessel composed of broken stone and clay. On the east side of the boulder, and in contact with it, were the remains of two skeletons which were badly decayed. The skeletons were on a level about two feet below the top of the mound."

Mound 11:
Lewis p.319:
"On October 31st, 1881, Mound No. 11… was excavated. It was elliptical in shape, 33 feet in length, 25 feet in width, and 20 inches in height. At a depth of twenty-two inches, and extending along the center of the mound for about six and one-half feet, were a number of decayed human bones, portions of six skeletons, and inter- mingled more or less charcoal and ashes. This is the only mound within the city limits that was distinctly stratified. The first or top stratum consisted of five and one-half inches of black loam; the second, eight inches of yellow clay; the third, about two inches of sand and gravel; and the fourth, four and one-half inches of black loam. The natural surface to the depth of about two and one-half inches, and covering a space ten feet in length and five feet in width, had been removed and then refilled with loam, human bones, etc."

Mound 12:
Lewis p.319:
"[October 31st, 1881] No. 12, which was 28 feet in diameter and two and one-half feet in height, was also excavated, and at the depth of two feet nine inches were the badly decayed portions of four skeletons, all in a conglomerate mass, and with them were a few small fragments of plain pottery composed of shells and clay."

Mound 13:
Lewis p.320
"[August 18, 1882], No. 13, which was 44 feet in diameter and 5 feet in height, was excavated. At the depth of two feet, and five feet northwest of the center, were portions of a skeleton, one muscle shell, one small arrowhead, and a piece of pottery composed of broken stone and clay. On the same level, two feet northeast of the center, were some fragments of human bones, including the skull, and a small chipped implement. At three feet ten inches, and three feet seven inches southwest of the center, was a skull, and on the same level, about four feet east of the center, was another, which had been placed in an upright position, and rested upon four large muscle shells. Scattered over this level were a few sections of vertebras, ribs, etc., but no two were together."

Mound 14:
Lewis p.319:
"[October 31st, 1881] No. 14, which was 28 feet in diameter and two and one-half feet in height, was next examined, and near the center, at a depth of two feet two inches, were parts of two skeletons. On the same level, five feet west of the center, were parts of two skeletons, and portions of three skulls."

Further notes: Lewis also located two more mounds (20 and 21) on the other side of Mounds Blvd that are not shown on the map above.

Winchell p.265:
"Mounds 20 and 21 are further northwest, the former 50 paces northwest from the corner of [the block between Plum and Hudson streets] and the latter near the corner of [Mounds Blvd] and Mclean St. These are large mounds but not more than one or two feet in height."

Winchell p.265:
"Mr Hill says: 'a few years ago, when [Mounds Blvd] was graded, aboriginal traces were discovered a few inches below the surface in the street at the head of the rise about opposite the west line of Euclid Avenue. They consisted of a fire-place (which I saw) formed by three small boulders near together, blackened by smoke, with ashes between them, and close by an old human skeleton in connection with which was a fragile clay pipe - no other relics that I saw or heard of. This may have been an obscure mound like those of Mr. [Lewis'] survey numbered 16 to 19 that [Wallace] and I failed to discover. Indeed there may have been others between 19 and the [Mounds Boulevard] hearth, but the natural surface of the bluff in the northern part of the blocks [along the bluff between Euclid Ave and Plum St] had been more or less affected by quarry roads, etc, and even at the time of our survey [1862], and was still more irregular when Mr. Lewis came on the ground [in 1881-83].'"
