 SOIL HORIZONS AND ABUNDANCE OF EXCELLENTLY PRESERVED LEAVES. KNOWLTON HAS SUGGES STED MIOCENE AGE OF THE FLORA. HAS NOT YET WORKED IT OUT. HENRY FAIR SHIPT HIM 10 APPLE BOXES OF SPECIMENS RECENTLY. 4RED YTIROTEIROS T SHALE AND SS INTRUDED BY BASALT. BOTH DIKES AND SILLS AND MUCH THAT IS JUST BIG GOBS. NO FLOWS. COLUMNAR STRUCTURE POOR, PLATY PARTING VERY PRONOUNCED. IS THE COLUMNAR STRUCTURE CHARACTERISTIC OF THE COLUMBIA LAVA FLOWS AND THE PLATY STRUCTURE OF COLUMBIA LAVA INTRUSIONS? BUT LITTLE BAKING OF SHALE HAS OCCURRED. HOWEVER, MINUTE CLAY COLUMNAR JOINTING HAS BEEN BORMED SOME OF IT VERY CURIOUS. IN THE CLAY JOINT BLOCKS, 3-4 INCHES IN DIA, AND RATHER IRREGULAR 3912 +RREGULAR IN SHAPE, ARE 100S OF SMALLERJOINTS, AT RIGHT ANGLES APPROXIMATELY TO THE SURFACES OF THE LARGER AND RADIATING FROM A CENTRAL CORE LIKE THE PORTIONS OF A PINETREE CONE. RUSSELL ALT HAS DESCRIBED THIS COLUMN-IN-COULMN IN THE COLUMBIA BASALT ITSELF. 398 NO BASE TO THE SHALE AND SANDSTONE EXPOSED. BUT PROBABLY IT IS IN THE BASALT SERIES. ENRY FAIR REPORTS A LOG BETWEEN FLOWS, FOUND IN SPOKANE, WHICH WAS SAWED INTO BOARDS BLACK AS EBONY BUT NOT CRUSHED OR SILICIFIED. GRAIN (SEQUOIA KNOWLTON) SHOWS PERFECTLY. CITY 1 MUSEUM HAS A SAWN BLOCK OF THISSANE LOG. MUSEUM ALSO HAS A COLLECTION OF LEAVES. 11 NONP SECTION ON EAST SIDE LATAH CREEK EXPOSES ONLY GRAVEL. SOME BLDRS SEEN IN THE GRAVEL, AS AT PANTOPS. SECTION DOES NOT EXTEND VERY FAR SOUTH BUT PROFILE OF BLUFF TOP AND CHARACTER OF SLOPE TO THE SOUTH SUGGEST THAT THE GRAVEL CONSTITUTES THE ENTIRE BLUFF AT LEAST AS FAR AS AQUILT JCT OF LAKE CREEK. BRINK OF BLUFF 2300+. THIS IS 300 FT HIGHER THAN ANY OTHER PART YET FOUND OF THE WISCONSIN VALLEY TRAIN IMMEDIATELY NORTH OF SPOKANE IT PROBABLY IS A PLATEAU WI CONTROLLED BY BASALT, VAH LIKE PLEASANT PRAIRIE AND FIVE-MILE PRAIRIE. 29048 STIHAR AND TAAT VOBA 19 BARONDO WON TI WO HOIT1803 Yeuo1v80 81 11 SPOKANE TO DARTFORD AUG. 1 1922 a 0800 GREAT VALLEY TRAIN GRAVEL FILL EXPOSED IN NORTH PART OF CITY.
