Lahaska Creek

Lahaska Creek (Lackawissa or Lahaskeekee) is a tributary of Mill Creek in Wrightstown Township, Bucks County, Pennsylvania. The Geographic Name Information System I.D. is 1178763, U.S. Department of the Interior Geological Survey I.D. is 02632.

History
The area was originally inhabited by the Lenape native americans as Lackawissa or Lahaskeekee, "the place of much writing". In 1718, Richard Mitchell purchased 70 acre and built a mill. It was replaced later by another mill known as Rush Valley Mills. After Mitchell, it was owned by Eldad Roberts, then by Joseph Watson.

Course
Lahaska Creek rises near the southwest border of Solebury Township from an unnamed pond north of the village of Lahaska. Flowing just a little over 100 feet, it enters Buckingham Township running southwest, then south, then southwest again, runs through five more ponds, and is supplied by two unnamed tributaries before its junction with Watson Creek forming Mill Creek at the Mill Creek 6.80 river mile.

Geology
The headwaters of Lahaska Creek begins in the Stockton conglomerate from the Triassic consisting of conglomerate and conglomeratic sandstone. Mineralogy is mostly quartz.
 * Atlantic Plain
 * Piedmont Province
 * Stockton conglomerate
 * Stockton Formation
 * Beekmantown Group
 * Allentown Formation

It quickly moves into the Stockton Formation also from the Triassic, which consists of sandstone, arkosic sandstone, shale, siltstone, and mudstone.

It then very briefly flows through a small portion of the Beekmantown Group, from the Ordovician, a layer of limestone containing dolomite, and chert.

Then it spends most of its time in the Allentown Formation, from the Cambrian. The Allentown consists of dolomite and impure limestone, siltstone containing calcium carbonate, oolites, stromatolites, and sharpstone.
