on each mountain flank. The Forge ridge division extends for about 5 miles up Licking creek and becomes united along the synclinal line with the same strata, outcropping on a southeast dip and making a terrace along the south side of the Blue ridge. The South ridge outcrop of the Ore sandstone creates a single terrace along the south side of Shade mountain, dipping southeast under the Mifflintown synclinal and appears again as the north division of the triple-crested Academia ridge.
The Ore sandstone in this ridge makes two parallel lines about a mile apart which coalesce over the crest of the Academia anticlinal just east of the Juniata river and north of Port Royal. This ridge is gapped by Licking creek and by a small stream west of Academia and several other branch streams create considerable notches either in the north or south flanks. The central portion of the ridge is composed of the lower Clinton rocks and Iron sandstone, which create broad rounded summits upon either flank of which the Ore sandstone, from 20′ to 25′ thick, creates narrow broken crests of white, gray and brown sandstone.
Fossil ore mines.
Along the flank of Blue ridge, west of the Juniata, the Sand Vein fossil ore bed has formerly been worked at several points.
At Milford siding, on the Penn. R. R., the Ore sandstone creates quite a distinct but low ridge and the ore bed, opened on a south dip of about 30°, had very little stoping ground and was largely hard ore. The bed was about 20″ thick here and laid almost directly upon the Ore sandstone.
About 1½ miles west of the river and nearly due north of the Lutheran church, on Licking creek, the Sand Vein has been worked at several places on Samuel Aughey’s farm. Peter Hiestand, of Newport, first opened the ore here and it was last worked by Wm. Nankewell, of Patterson, in 1886. The Ore sandstone still makes a distinct ridge at this point and the slope is so gentle southwards that no great length of breast could be obtained in working the ore. The various drifts are now pretty well fallen shut, and the
