The Saccharoida! Sandstone. — Broadhcad. 107 
On bluffs of Lost creek, Warren county, one and a half 
miles from the Missouri bottoms, the section shows : 
■ I. 57 feet with outcrops of chert and some sandstone. 
2. 20 feet of Devonian Hmestone. 
3. 15 feet of crinoidal limestone. 
4. 80 feet of Trenton limestone. 
5. 31 feet of First Magnesiaii limestone. 
6. 70 feet of Saccharoidal sandstone. 
7. 105 feet of Second Magnesian limestone. 
On Charette creek, Warren county, the Saccharoidal sand- 
stone is seen 84 feet thick, the upper part white, the lower 
brown tinged, and forming very picturesque scenery, and cov- 
ered with lichens and ferns. Springs of water often issue from 
the lower beds. 
The Saccharoidal sandstone is exposed on most of the 
streams flowing towards the Missouri in Warren, Montgomery 
and Calloway. Five miles southwest of High hill, there is a 
lone hill called the "pinnacle'' nearly surrounded by the water 
of Pinnacle fork. It is 88 feet high, with a width at the bottom 
of 100 feet, and 540 feet long, the lower 50 feet nearly per- 
pendicular, the upper 12 feet of First jNIagnesian limestone, 
that below of sandstone. The lower part of the sandstone is 
sometimes deeplv weathered and forms good shelter for cat- 
tle. 
On Whitesides branch it forms very picturesque escarp- 
ments capped by the First JMagnesiaii limestone. On Dry 
fork of Lowtre it forms beautiful terraces and escarpments, 
the upper 4 feet columnar. The columnar was also seen on 
Lost creek in Warren county and on most of the branches of 
Loutre river. The best example of this was seen on Whetstone 
creek west of Loutre. 
On the Missouri bluffs, near Portland, there is a shallow 
cave in sandstone known as Saltpetre cave. Saltpetre has been 
made here and the walls are coated with a fine ^\hite efflor- 
escence. 
At the Clatterbuck ford, on Cedar creek, line of Boone and 
Calloway, the section shows : 
1. 52 feet of Devonian limestone and shales. 
2. 25 feet of First Magnesian limestone. 
3. 30 to 40 feet of Saccharoidal Sandstone.
