El Tepalcate, an archaeologic site on a low flat peninsula situated just off the eastern shore of Lake Texcoco and near the town of Chimalhuacan, is the site described by Ola Apenes in the preceding article.

The excavations made at the site consisted of fifteen separate pits and trenches by which an attempt was made to find stratified materials and to determine the nature of the circular heaps of stone and the alignments of stone forming large rectangles which are the only architectural features visible on the surface of the site.
