In Colorado SO square miles OF now

1906, Two parties, one under Mr.
Frank Tweedy and ono under Mr.. Pear
son Chapman, were engaged In topo-
graphic work in the Black Hawk quad
rangle, and In the Idaho Syringe, Silver
Plume and Central CITY Special quad

contour interval OF 100 feet, and tho work
in the special quadrangles was for pub
lication on the scale OF 1l2C00. with a
contour interval OF 100 feet. and the work
In the special Quadrangles was for pub
hcation on the scale OF l.l2O0D, with
contour interval Of 10 feet topo-

were engraved and printed during the
year. These included maps of Cripple

engaged In surveying the San Cristobal
quadrangle. In the office Mr.. CrosS's
ume was partly occupied by problems
connected with the corrclc tlon OF tho

and by matters relating to the publ!ca-
ton OF the Sllverton, Needle mountains

Tracing Utah Formations
Under his supervision tho Ouray folio
was prepared by Mr.. Howe assisted by
Mr.. Emmons, and submitted for publ
cation by Mr. Cross. The last month Of
the fiscal year was devoted by Mr. Cross

for the purpose of tracing several Meso-
Zoic and Paleozoic formations from the
western front OF the Rocky mountains
into the plateau province OF Utah, with
view TO their correlation. In this re-
eeonnaiss3ncG MI Cross was ae~sted by
MeSsrs. L. II. Woolsey, w. II Cmmons
and C. F Kay. A general examination
OF the Florence oil field was made by
Mr.. y. NJ. Fenncman, who also paid a
brief visit TO the Boulder oil field. The
results Of the observations on the Flor
ence field were Incorporated In a brief
report published in the annual economic
bulletin. Preliminary and detailed re-
ports on the Cripple Creek mining dis
trict were prepared Jointly by Messrs
Waldemar Lindgren and F. L. Ransome.
Gauging Mining Streams.
The areal and economic geology Of the
mining regions OF Clear Creek and Gllpln
counties was mapped by two field parties
under the direction of Mr.. j E. Spur.
who was assisted by Messrs c. H. Car
rey, n F Clark, s. H. Ball and Oscar
II. Hershey; During the field season the
areal mapping OF the Georgetown quad
Iangle and OF q portion OF the Central
City quadrangle WIS completed: also the
study OF the mines OF the Georgetown
quadrangle and OF the Empira district In
the Central City quadrangle. Gauging
stations for the measurement OF streams
were maintained by the survey at the
following places; Durango. Canyon City

Artesian Wells Attract Attention.
Much attention was devoted during the
year TO the subject OF underground water
supply in the State, and Investigations
were made in several districts. The ar
tesian area OF the Arkansas valley in the
eastern part Of the State was studied by
Mr.. n II. Darton. In order to ascertain
the limits OF the district in which flows
are obtainable and the volume Of water
available. The geologic structure was
determined, so that tho depths or the
water-bearing strata can be predicted
with fair deGree OF accuracy. The re
port which was prepared a result OF
this study is accompanied by maps show
Ing the geology. depths TO Dakota sand
stone, wells, flow area. intake zone and
by cross sections which illustrate the un-
derground relations.
Water in San Luis Park
c f. Siebenthal completed a detailed
examination Of the artesan basin in the
San Luis park. and the report will soon
he ready for transmittal The water from
aTtesinn wells is most important feature
In this valley, and much interest Is mani
tested In the extent Of the flow area and
the volume OF water available. AS wells
are very numerous, and large volume of
water Is flowing from them, special con-
sldcration was given to the question OF
the source and pcrmanency Of the water
supply In view OF the extensive rcclama-
ton works now in progress in the Uncom-
pahgre valley. II deemed desirable
u investigate the underground waters
upon which many OF the settlers must de-

tanning the conditions relating TO under

portions OF the region watcr-bcaring

districts they may be expected to furnish

No New Work in Idaho.
