Repokt of the State Geologist. 



in Neweomb. Much sand and gravel also occurs north and south of Minerva 

 post office, but in the portions of the town that were studied, it must be 

 admitted that the glacial deposits furnish much less of interest than in the 

 towns farther south. 



Mines. The one little iron-ore prospect referred to under Series I and 

 II, was the only one 1 met. The quality of the ore precludes its working. 

 Professor Smock mentions a vein northwest of Olmsteadville that was opened 

 by the Burden Iron Co., in 1881, but that is only of small size (Bulletin 7, 

 New York State Museum, p. 36). The only other mineral of importance is 

 garnet, but the present developments for it lie mostly just outside of the town, 

 in Warren county. The one prospect that I saw was high up on the precipitous 

 cliff in the southwestern corner. Although I noted the small dump in the 

 talus while passing at a distance, I did not learn what it was until after I 

 had returned to Minerva. No doubt the region is favorable for the mineral, 

 and some deposits may yet be opened up but, as stated, present developments 

 are in Warren county. The following brief accounts are all that have yet 

 been published about them. F. C. Hooper, " Garnet as an Abrasive," School 

 of Mines Quarterly, January, 1895. D. Van Ingen, "New York at the 

 World's Columbian Exposition," p. 341. Further study of them will be of 

 economic importance as well as of scientific interest in illustrating one of the 

 minor results of the general metamorphism. The limestones have certainly 

 been important contributors of their substance toward the formation of the 

 mineral. 



Neweomb. 



Topography. Neweomb is a very large and sparsely inhabited township 

 that lies along the western border of the county. In its northeastern corner 

 it contains the headwaters of the Hudson in lake Henderson and lake 

 Sanford, and in lake Colden from which flows the Opalescent river. Several 

 high peaks are in this section, for the summit of Mount Mclntyre, at 5,112 

 feet, is just across the line in North Elba, and its southerly ridges at 4,855 

 feet and less, stretch Avell into Neweomb. Santanoni, reported at 4,644 feet, 

 lies some miles westward and is an impressive peak because comparatively 

 isolated. Coming south along the eastern border, the valley of the south 

 branch of the Opalescent liver is a fairly open one, and is succeeded by the 

 North River mountains, a ridge 3,814 feet at its summit. Minor spurs are 

 characteristic of the southeastern portion, with one good sized lake called 

 Perch pond. Along the southern line the elevations are moderate, but the
