a tunnel. Lot CN1 is from shale in the middle part of the formation on 
McGillivray ridge. Section DH is at Hell Gate on Castle river, South 
Fork map-area. Lot DH1 is from 25 feet above the basal sandstone there. 
Lot DH2 is from about the middle of the formation, and from 300 feet 
(estimated) below the top. Lot CN2 is from the Kootenay formation at 
the forks of McGillivray creek; the horizon is not known. Lot DG1 is 
from a parting in a coal seam exposed in an open pit on the north bank of 
Castle river, west of Well’s ranch and on the Carbon Hill property. Lot 
DG2 is from shale at an horizon higher than DG1 on the south bank of 
Castle river near the above locality. 
Many of the species have a long range, although most are confined to 
the upper half. The following 5 species range throughout the formation; 
Oleandra graminaefolia, Cladopklebis montanensis, C. virginiensis, C. hetero- 
phylla, and Pterophyllum acutipennis. The following 3 species range 
throughout the upper half of the formation: Onychiopsis psilotoides, Podo - 
zamites lanceolatus , and Ginkgo arctica. The following ranges through the 
uppermost quarter of the formation: Csekanowskia sp. The following 3 
were found only at the top of the formation: Coniopteris pachyphylla, 
Nilsonia schaumburgensis, and Nageiopsis angustifolia. Tbe following 
were found only near the base of the uppermost quarter of the formation : 
Acrostichopteris Jimbriata and Nageiopteris zamioides. The following occur 
only in the middle of the formation; Cycadolepis sp. and Baiera sp. 
Lot CQ2 is from shale below a thick sandstone at the base of the 
formation on York creek and contains : Athrotaxopsis grandis and Nageiopsis 
(?) montanensis. 
LOWER BLAIRMORE FLORA 
The flora found in the lower and greater part of the Blairmore formation 
numbers 28 species and is chiefly an old flora similar to that of the Koot- 
enay, but with the addition of very -rare angiosperms. It contains ferns, 
cycadophytes, conifers, and dicotyledonous angiosperms. The strati- 
graphic position of this flora is shown in the table, page 90. 
Section CH is on the east slope of Ma butte, where an almost con- 
tinuous section is exposed in gullies, etc. There plants were collected at 
eight levels, at seven of which, from 450 to 1,360 feet, the flora here desig- 
nated as the lower Blairmore flora was found. The fossil lots from these 
levels are numbered CH2 to CHS. Lots DAI and DA3 are from the 
banks of Castle river, just above the mouth of Link creek, at the levels 
below the Crowsnest volcanics indicated in the table. Lots CS1 and CS2 
are from the lower part of York creek, downstream from a ranch house, 
south of the railway and west of Blairmore. Lot CU1 is from the lower 
part of the formation, on the upper part of York creek. Lots DB1 and 
DB2 are from the north bank of Castle river, east of the (Hell Gate) canyon 
and west of the cable footbridge on the Carbon Hill property. Lot DB1 
is estimated to be about 800 feet above the base of the formation and DB2 
is about 100 feet higher; owing to overturning and folding exact measure- 
ments are not possible. Lot DF1 is from shales of the Blairmore on the 
north bank of Castle river at the <4 Paint mine” east of the Cole ranch;
