Excerpt: ...same terrace rises steeply from the low river flats to the heights at Arlington and Fort Myer, where its level floor extends back for several miles to the slopes of the earlier (Pliocene) high plateau. To the eastward there are fragments of the terrace constituting an area of considerable extent in the vicinity of Saint Elizabeth's Insane Asylum. This terrace level is always sharply separated from the lower terraces on which the older portion of the city is situated, by steep slopes such as those extending along the north side of Florida Avenue. These slopes were originally the boundary of the city and for many years proved a barrier to street extension and the expansion of its settled area. Now, however, many streets have been graded up the slope and the admirable high ten-ace above promises to be well settled. The lower or later terraces extending from tide water to a height of 100 feet have great width at Washington, and they extend for many miles up the Anacostia river and down both sides of the Potomac river to its mouth. The city of Alexandria is built upon one of the lower levels on the west side of the river, 7 miles below Washington. Ascending the Potomac river above Georgetown we find that the lower or later terrace continues up the gorge through the crystalline rocks of the Piedmont plateau. Owing, however, to the hardness of the rocks the entire river trough in this region is narrow, and the remains of this terrace are an irregular bench of slight width extending along the north side of the river at about 100 feet above the water.
