Where trail E. from Forest Glen (six miles) strikes the Desplaines river there is a large spring, equal to the pool in Riverside, which undoubtedly increased the depth of the river, it having here the appearance of a deep canal with precipitous river banks immediately north of the spring and about half way between it and the north line of the section, (corresponding to Center St, in Park Ridge) the top of the knoll is not more than three hundred feet east of the river.
This knoll seemingly had been improved into a terrace, to the extent of one acre by a trench two feet deep which surrounded it on four sides in the shape of an arrow head minus the point, the butt end lying towards the river and the setting sun in October. A sacred enclosure similar to those in Ohio, says our friend Carl Dilg. In the south centre of the enclosure there is an Indian mound, twenty five feet in diameter and probably eight feet high in its former state. About one hundred feet to the northwest and also within the enclosure there is a similar mound of half the size of the former; a liitle West of which was the third mound still smaller, but now past locating. Depressions or holes about two feet deep, to the number of thirty, were found promiscuously along the west border of the enclosure the most of them between it and the high river bank.
About two hundred feet north of the enclosure, Mr. Lempke the proprieter of the grounds, found several bushels of "little white stones" (flint chipps) in a heap, which he buried on the spot. He thought it a great hardship upon himself and son to scrape and plow to fill up "those holes and ditches" and level of the mounds in addition to clearing the ground of a heavy growth of timber and in his estimation the work is still unfinished.
The approximate elevation of the several Indian mounds mentioned here, above the level of Lake Michigan is respectively at Park Ridge which is the highest -- seventy feet -- those at no. 4. fifty feet -- and Harlem and Riverside about forty.
In regard to the value of these mounds being what men of knowledge and science supposed them to be Viz: The work of ancient mound builders of America -- some investigation was made before 1871, of those at No. 4. & No. 9. and mentioned in the public print of that time.
A member of the Academy of Science Dr. Edmund Andrews quoting only from memory says: "That archaelogical specimens from the mound builders at the Desplaines river were in the museum of the Academy of Science which was destroyed by the great Chicago fire in 1871, as were also the records of the society, but Dr John A. Kennicott or Sec. Stimpson may have left a record in some of their works."
"These mounds were built by a tribe of Indians which built mounds. In the Northwest of the present day there are several tribes who built mounds. The mounds here were not claimed by the Indians and they could not give any account of them, but the pieces of skull found did not differ from those of our own Indians."
The mounds at Park Ridge partially examined by different parties with permission of Mr. Lempke shows the plain Indian inverted with his weapons ready for the happy hunting ground. The large mound today is discernable from the wagon road on the south and is still about three feet high. The trench can be located on the north, also on the southwest corner opposite the road.
Of the mounds at Indian village No. 4, four of them can yet be discerned the fifth one being mostly cut away in building the public road, when an Indian skull is said to have been found as related by Mrs. Rusell.
We have shown that these monumental mounds were well located also with referance to the proximity of the highth of land, to the mouth of Chicago river and the elevation of Lake Michigan in all ages. Being situated in an ancient bayou from where a direct route would cross the highest part of the Chicago plateau.
The Park Ridge Indian village was well located as a way-station on trail E. & D. running to the Fox Lake country and the Kishwaukee valley. The trail passing the spring runs right through the Indian village, crossing the Desplaines river in Sec 28 town of Maine, as did the stage coach in pioneer days, coming up from Chicago by way of the six mile house (John McLean).
The product of the chipping station here, as well as that at No. 4, was of a superiour order. The large number of small war points might speak for war parties from the north as Thornton does from the south. But the remains of Indian pottery are more plentyful that at any village yet spoken of -- There is known to be a large supply of blue clay in the vicinity.
The scenery here is grand, there being here also a magnificent slope to the south where the river is shallow and gravelly and the shore is clean. This village like no. 10 & no. 14 is within the ten mile limit of the Lake Shore where the air is clear, the stars bright and the woods plentifully supplied with birds of plumage and song.
