Patterson Heights: From Ice cap to settlement

The Foundation

     Much of the final conformation of Patterson Heights, of Beaver

County, of Western Pennsylvania, and indeed of the whole Northern

Hemisphere, was a result of the great northern ice cap formed during the

glacial periods. Expanding and contracting through the millennia, like a monstrous gelid amoeba, it scoured the land beneath.

     By the end of the last glacial period, 10,000 years ago, the wall

of ice impinged on the northwestern corner of Beaver County, the terminal

moraine extending from Koppel southwestward across the southern portion

of South Beaver Township to the present Ohio line.

     The effects of the glacier were considerable, but the

foundations of our area were planted in rock laid down some 300,000,000

years ago, prior even to the formation of the Atlantic Ocean. Sand and

clay, later under pressure to become shale and sandstone, were deposited

as erosion products from a massive mountain range to the east. The coal

and petroleum deposits found in more modern times are testament to the

periods when lush vegetation covered the land, and limestone beds were

formed on the exoskeletons of shellfish during periods of submergence

below the sea.

     The Homewood Anticline, a fold and resultant thickening in an

underground sandstone layer near Homewood, bears witness to the

formation of the Atlantic Ocean and westward tectonic movement of the

American continent. The east coast's moving faster than the west resulted

in buckling of the surface, and the Appalachian Mountains are a present

day manifestation. Underground, the Anticline represents a result of the

same asynchronous movement.

     The Allegheny Plateau, of which Patterson Heights and Beaver

County are a part, lifted above the surrounding area, floating on a sea of

lava. The elevation, erosive forces, and rain created a generous system of

waterways, even in pre-glacial times. However, the drainage was north

into a large ancestral Erie Basin. The Monongahela River flowed north,

and was joined by the lower Allegheny at Pittsburgh, and continued north

up the Ohio River Valley, just as today. At the Beaver, however, the flow

continued north, instead of south as it does now, through the present

Beaver and Mahoning River valleys and thence through the Grand River

Valley to Lake Erie.

     The ancestral Ohio River arose south of Wheeling, and flowed

north along the Ohio River Valley, joining the Monongahela near Wampum.

The middle and upper Allegheny Rivers, rather than flowing into the lower,

as today, also flowed north, and emptied directly into the Erie Basin.

     A massive upheaval of land north of Beaver County and the

encroaching glaciers dammed the northern flow, and for years much of

Southwestern Pennsylvania was covered by Lake Monongahela.

Eventually, glacial waters found their way to the Mississippi and Ohio River

valleys, thus draining Lake Monongahela, and resulting in our present

drainage system.

     Although the glacial advance had more effect on the lands

north of us, much sand and clay washed downstream subsequent to glacial

melting. The deposition of these products and rapid down-cutting, as the

result of flow reversal and glacial melt, resulted in the high terraces along

the lower Beaver, on which towns, such as Beaver Falls, were built.

Early History: Cowboys and Indians


     Those of us who, in our youth, scoured the Alum Rocks, and overturned shale along the sides of the Incline searching for Indian arrowheads, had no idea of the age of our discoveries; but some of these artifacts may have dated to the time of the Monongahela people. These prehistoric denizens of Beaver County have been dated back more than 6,000 years, and may have represented the first citizens of Patterson Heights. W know little of these prehistoric people, however, for they disappeared without a trace sometime early in the seventeenth century.

     The flints we unearthed, however, were probably the work of the Delaware, who migrated to this area in the early- to mid-eighteenth century. Dispossessed of their land along the Delaware River in eastern Pennsylvania by the Iroquois, they were forced further westward by continuing pressure from white settlers. Their initial settlement in this area was on the Allegheny River in Kittanning in 1725, but near the middle of the century, the principle part of the tribe settled at Sawkunk—present day Bridgewater—and Kuskuskee, near the confluence of the Mahoning and Shenango Rivers, where they form the Beaver. The Delaware were joined during this period by the Shawnee, another serially dispossessed people, and remnants of Wyandott, Mohican, and other tribes. The powerful Iroquois nation maintained a presence in the area as well, and, according to Washington’s Journal, such famous chiefs as Tanacharison and Monakatoocha, resided at Logstown.

     The Seven Years’ War, as it was known globally, or the French and Indian War, as it was known in this country, forced the Indians to take sides, and the Iroquois maintained their longstanding allegiance to the British. The Delaware and Shawnee, long the enemy of the Iroquois, aligned with the French. Their brief occupation of Beaver County ended in 1758, when, following the fall of Fort Duquesne, General Forbes drove them into Mahoning County and other parts north.

     The settlers of this area were not to be so easily freed of Indian conflicts, however. Pontiac aroused the Indians in 1763, and the frontier was again terrorized until the campaign of Colonel Bouquet, who camped in this area at Tuscarawas before proceeding to eastern Ohio to inflict an overwhelming defeat on the Indians. In 1774, the acquisitive governor of Virginia, Lord Dunsmore, attempted to clear the upper Ohio of Indians. His goal was the takeover of much of present day southwestern Pennsylvania, including the southern portion of Beaver County. The plan backfired badly, however, and in the end the Indians countered by driving most of the settlers east of the Monongahela.

     The shot fired at Lexington, and heard “round the world,” reverberated less resoundingly in the west, as the main conflict never spilled over the Alleghenies. The Iroquois, however, remaining faithful to their British allies, increased their raids on the settlers. At this point, a name to become famous in Beaver County history was introduced with the appointment of Brigadier General Lachlan McIntosh as commander of the Western Department, headquartered at Fort Pitt. McIntosh arrived with a large contingent, charged with subduing the western Indians, and capturing the British garrison at Fort Detroit.

     In the fall of 1778, in preparation for his proposed campaigns against the Indians, McIntosh established his now famous fort at the site of present Beaver. That this undertaking was not universally acclaimed may be deduced from the words of Colonel Daniel Brodhead in a letter to General Armstrong:

     “…and it was owing to the General’s      determination to take Detroit, that the very romantic Building, called Fort McIntosh, was built by the hands of hundreds who would have rather fought than wrought.”

     This is the same Daniel Brodhead who was a member of McIntosh’s staff, and who would relieve him in the following year as commander of the Western Department. He was also the same Daniel Brodhead for whom Brodhead’s Road, the first road from this area to Fort Pitt, was named. In 1794, he would purchase 800 acres of land extending westward from the Beaver River and including the lower end of Beaver Falls, much of Patterson, and the present-day Patterson Heights.

Unfortunately, the cessation of the Revolution in 1783 did not mean the end of the Indian troubles along the frontier. The Treaty of Fort McIntosh in 1785, along with that at Fort Stanwix (Rome, NY) the year before, negotiated the purchase of most of Western Pennsylvania from the Indians, as well as the return of prisoners from Fort Detroit. These treaties represented the first made between the Indians and the United States, but were promptly ignored by the Indians. Said Colonel Brodhead:

     “…and the Indians of the Miami confederation gave great annoyance. The army of General Josiah Harmar (1789) and that of General Arthur St. Clair (1791), which had been sent against this confederation, had met with frightful defeat, as a consequence of which the national government was humiliated and the whole country plunged in gloom.”

     Emboldened by success, the Indians increased their harassment along the frontier. The situation became intolerable, and President Washington selected the Commander in Chief of the Army of the United States, Anthony Wayne, to lead an expedition against the Indians. Known as “Mad Anthony” for his tremendous energy and his extreme daring in battle, Wayne began organizing an army known as the “Legion of the United States” at Pittsburgh in 1792. The army proceeded down the river and camped that winter at the now famous site of Legionville in Beaver County. In the spring of 1793, he continued on to Fort Washington (Cincinnati), and finally gave the Shawnee (et al) a severe mauling at the Battle of Fallen Timbers on the Maumee. The Treaty of Greenville ended the Indian hostilities north of the Ohio, and opened the entire area for further settlement.
