Relative position GO 5.5 MI NW OF KNOX CITY TO BRIDGE OVER BRAZOS RIVER ON TEXAS HWY. 143 (222). GO 4.8 MI NW ON HWY. 143 TO MCFADDIN LANE. TURN NE FOR ABOUT 2 MI TO WHERE ROAD JOGS N. TURN ON ROAD TO WNW FOR 0.65 MI. TURN N. AT FORK FOR 1.2 MI TO NW TO FORK. GO N. AND E. FOR 0.25 MI TO CORE HOLE C-10 ON N. SIDE OF ROAD. GO E. 0.1 MI, THEN N. 0.45 MI, WHERE SAMPLE 14 WAS TAKEN. ABOUT 3200 FT TO ESE IS LOCATION OF MCFADDIN PROSPECT, ACCORDING TO SMITH (1974, MAP III), BUT IT WAS LOCATED IN SEC. 29 BY STROUD AND OTHERS (1970, P. 37)? THE PROSPECT WAS NOT A MINE, BUT THREE, 12-FT LEACHING TANKS, BUILT IN 1945. ABOUT 0.5 MI N. (BY ROAD) OF SAMPLE 14 SITE, ON N. SIDE OF LITTLE CROTON CREEK (MUSTANG CREEK), W.
