The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1913-06-12

The act making appropriations fol
the sundry civil expenses Of the gov
eminent for the fiscal year 1901 in
cluded an item providing for the min
eral classification of certain lands
within the limits of the Northern Pa :
cific railway company's grant, for
which title under the original grant
had been withheld pending such class
ification. The examination Of these
lands was assigned to the geological
survey. A considerable area specified
for classification is situated in north
ern Idaho, mainly in the drainage ba-
sin of upper st. Joe river. lying adj
jacent to and south Of the Occur
d'Alene mining district Three geo.
logic parties and one topographic party
spent a short and on some accounts
unsatisfactory season In this particular
area. Owing to the unexpected nature
Of the assignment the work was late In
starting, and on account of forest fires
the season proved to be one Of the
most disastrous to life and property
that has ever been known in this heav-
lily timbered country. considerable
part Of the area was reviewed howev-
err, and the present report is a sum-
mary Of the general evidence that has
been collected. The map Is based on
the control established by j, E. Black
burn of the geological survey and the
geologic work is compilation of the
results obtained by F. c.. Calkins and
G. F. Loughlin in the area south of
st, Joe river west of Avery; by D. F. |
