NEW ALASKAN MAP.
Especially Designed by the Government
Tor Prospectors, Miners and Trav-
elers in the Gold kegiors.

A map of Alaska. showing gold-bear-
ing rocks. with descriptive text con-
tanning sketches of the geography,
geology and gold deposits and routes
to the gold fields, has just been issued
by the United States Geological Survey,
in pursuance of a recent joint resolu-
ton of cogress. 1t can be "a for the
asking.
The map. which is on "A scale of 81
miles to the inch. Is specially designed
for the use of miners. prospectors, n
travellers i'm Alaska. The region repre-
scented extends from Boring strait
eastward to the Rocky mountains n
British Columbia. and from the 54th
parallel northward to the Arctic ocean,
embracing the drainage basin of the
Yukon river from its mouth to it's
most distant headwaters. The princi-
pal topographic features. as plateaus,
mountain regions N valleys. are in
Dictated. More Is known of the valleys
and regions bordering the n~avigable
drainage ways thar of other portions
of the country. Back from the rivers
lie extensive rugged tracts still COM

The lines of magnetic variation are
laid down. The Fort 81. Michael mill
tary reservation. on the coast. is out
lined. The center of his reservation
is st. MIchael island, and IL includes
the great delta of the Yukon. the head
of Norton sound, and Golofnin bay.
The map includes two smaller, local.
larger-scale maps, one OF the Forty
Mile and the Klondike gold-mining re-
regions, the other OF the mountainous
area tive the coast and the inter
ior above Lynn canal. showing the
passes. routes and trails leading from
the tide water to the headwaters of the
Yukon. 1t is i'm part colored, showing
at a glance by color and by name where
gold and coal have been found. in both
the interior N the coastal regions,
especially the gold-bearing rock forma-
tons of the Forty Mile and Birch creek
series. These collaborating rocks are
seen to trend from the Klondike region
for neaIIy 800 miles northwestward,
across the great elbow of the Yukon.
toward the coast.
The descriptive text accompanying
the map. consisting of ~ pages. con-
aim useful information for the practi-
cal p~rospector and miner. 1t gives a
brief historical, geographical, and geo.
logical sketch Of the country describ-
ing it's rivers, mountains. climatic con-
ditfons, routes. trails and passes. with
valuable information, hints and direc-
ions to the travele down the Yukon
concerning the canyon and the danger
Gus White Horse rapids. Besides the
rock formations of the Forty Mile and
the Birch creek series. the original de-
posts. or collaborating quartz veins.
are broadly discussed and the probable
extent of the gold deposits is indicated.
Similar consideration is given to the
detrital or collaborating placer gravels
and to the mode Of concentration of
the coarse gold. it's nature, and the
manner of it's extraction. Valuable
metals other than gold. as platinum
and copper. are also touched upon. The
deposits of coal and Ignite are men,
toned somewhat fully. They occur
mostly i'm the coastal regions and on
the lower Yukon, though good coal is
also found i'm the Forty Mile district,
ms on Coal creek. Similar deposits
have also been reported on the head
waters of the Stewart river, just above
the Klondike w. +. NJ.
