(150 - 200 yds distance) 17 Next northern knoll overlying the foot of cliff is a banded rock but a glance at quartzite with mica mica in it 679 Climbed 30-40 yds here + then collected Sp. 680 - Micaceous quartzite(-) examining small fawned dikes. 575' A.T. If these be really quartzite the Hu- norion is to be carried up to the top of this cliff east of igloo at Canyon Lake - underlies big spurs, Loose blocks of unrecognizable quartzite die on top of the eastern knoll (form- ing west side of gulch) at brow of cliff 700' A.T. I would swing quite westward along brow + turn boundary northward near head of gulch directly above Pridtla's igloo, or around again the higher point nice cairn was built which seems to be genuine. 3:30 p.m. Base of cairn 760' A.T. Cairn measures 7'3" high on east side 28 June. Climbed shallow gulch and face of cliff 200-300 yds east of Pridtla's igloo and found Hunorion quartzite and schist forming upper 200 feet of the bluff. Is there a fault between this knoll and the cairn cliff, traversing and causing the large gulch directly above the igloo?
