proNimately eight miles, where the
antlCnne terminates in fault, are
large seepagcs ana paraffin residue
patches. In the Salmon creek as in
the Wide Bay domes of the coastal
anticlnes, the Naknek formation is
missing and at least 5000 feet OF
the Upper Jurassic is exposed. over
a very small portion OF the Wide

The Middle Jurassic Ia not known
to appear elsewhere on the penin-

end OF this antiCline, where the up

lower Jurassic which in turn Is
superimpoeed upon the Triassic.

Near its northwest end Is a sharp

covered with rocks OF the Naknek
formation, here estimated to he
1,400 TO $500 feet thick, and the
oil beds within reach OF the drill

of tho Upper Jurassic. Many seep-
ages occur on the Pearl Greek"
structure.

cate favorable ground for the oil
prospector as many seepages are
known to exist throughout the en-
tire length of the peninsula The
oil from these seepages which has
been examined by many chemists
in the states shows a paraffin base

Oil
The residue beds that exist on the
Trail Creek and Pearl Creek domes
I'm many instances cover several
acres to a depth Of from ten to
twenty feet and provide a source Of
fuel for nearby drilling. This resi-
due, paraffin n-soaked-moss and in
places practically pure paraffin un-
der the heat Of the sun becomes
semi-liquid and in cold weather, it
retains It's elasticity and gives read
ily under pressure of the foOtstep.
The most OF this oil seepage Is
coming with water and the seepages
vary from several gallons to few
barrels per day each. The forma-
tions are not badly faulted, though
several large faults do exist! The
sedimentary beds are cut in few in
stances by dikes and sills of acidic
intrusive rocks To the northwest
of the Pearl Creek dome, Mount
Peulik, a recent though inactive vol
-cano, has broken through the upper
JurassiC beds, and there are some
lava flows spread over. the surface
OF the sedimentary rocks.
Recent volcanic activities have oc-
cured some 80 miles north of the
Cold Bay fields in She eruptions OF
Mount katmai and Mount Mageik.
Mount Shiginagak OF Wrangle, some
fifty miles southwest of Wide bay
is an old but still active crater. These
volcanoes in no way effect the struc-
ture under discussion and, with the
exception of the vicinity OF Mount
Peulik, there is to be found no lava
flows or volcanic rock. Along the
coast, especially on the capes to the
east Of the Wide Bay structure min
eralized dikes appear in the sedi-
mentary formations. These dikes
are characteristic OF the entire
southeast coast OF the Alaska penin-
sula.
That these structures on the
Alaska peninsula will be the source
of a productive oil field, is the pre-
diction and expectation of practical
ly every geologist that has visited
the peninsula, aud a great many
prominent petroleum geOlOgis.s
have. In recent months, visited the
field.
Prior to 1904, there was drilling
In both the Inskin Bay and Cold
Bay fields. In both instances how
ever, no attention was paid to
geology aud wells were not drilled
on structure. COnveniences o
transportation, the presence of
seepage and a driller's hunCh seemed
to be the main guiding points in
their locations. At Cold Bay the
wells drilled by Costello in 1903 are
at least six miles from where any
possible location would be made by
a petroleum geologist operating
today.
Cost Not Excessive.
'The cost OF development in this
field at first glance seems 20 be a
serious objection" Mr.. Parry says
but there is nothing that would
deter anyone who has operated In
the Texas or California fields from
operating there and when careful
consideration is given 10 the trans
portation most Of the objections
that have been raised, cease to exist.
The southeast coast of the Alaska
peninsula IS favored with many
splendid harbOrs though at present
they are unsurveyed and have no
harbor lights or charts that would
warrant a navigator taking his Yes-
sci into them. Fishing and Cannery
boats, however, visit these harbors
1 frequently and at present the mail
steamer Starr" stops regularly at
most OF them.
The cost OF laying down freight in
| cargo lots from Pacific coast ports
will be less than was the cost Of
Transporting of freight into Breck-
