Not illustrated. 1904 Excerpt: ... 850foot level; but the majority lie between these limits, more often near the 900-foot level. This difference in elevation is readily accounted for, on the grounds of subsequent erosion. The ridges rise to greater elevations in most cases. Dr. Hayes has previously noted the uniformity in altitude, of these deposits, and has discussed its significance and bearing on their possible age, which is elsewhere discussed in this report.1 The following is a list of the known deposits of bauxite in the Bobo district: --Locat1on And Descr1pt1on Of The Ind1v1dual Depos1ts The Cave Spring section, as is shown on the accompanying map, includes three deposits, grouped along a north-south line, within half-a-mile of each other, and not more than two miles a little east of south from the town of Cave Spring. These form the most southwesterly known deposits in the State, and are within a comparatively short distance of the Alabama State-line. While they are removed some little distance from the Bobo district proper, they are properly grouped in this district, on geologic grounds. Their mode of occurrence is geologically identical with those of the Bobo district. They form the most interesting series of deposits in the State, from the standpoint of erosion, which furnishes a possible clue to the vertical limits of the ore-bodies. The most northerly deposit has the greatest altitude above sea-level; and field-study indicates, that it has suffered but little, if any, erosion. The most southerly one, on the other hand, is in a deep valley of erosion, 170 feet below the northernmost deposit, and half-a-mile distant therefrom. After being worked to a depth of 20 feet, it is entirely exhausted, indicating that nothing more than the remnant bottom portion of the deposit was left, th..
