THE NENANA COAL FIELD, ALASKA,

By G, C. Wm.

O E a e m *

The Nenana coal field lim in latitude 64' N., longitude 149' W., in the northern foothills of the Alrtska Range, which form a balt abut 20 mi388 wide between the h i h mountains and the iowhda of the Tmana Vdey. This foothill area ia rugged and includes a sari- of nmly parallel ridges and intemening areas of lees relief. Most of the coal area are in lowland tracts that lie between the foothill ridgee and am drained by w t w d or weatward flowing tributaries of the major stream, which head in the high mom tains and flow northward across the foothill belt. (?me PI. I.)

Nenans River, the lgest stream in the area, h d 8 south of tbe Alaake R q p and flows northward to join the Tanana at Nenans. 19'velEey, which aPEords a line of communication between the vdey of the Tanma and the southern mast, js followed by the Gnvemment

. &npl now under construction. Amox the larger tribrrtariea of Pu'enana River from the esst and west are Hoseanna w i t e ) h k nnd Healy h k , which dmin two of the principsl cad mlra. The coal lands in the Palley of Hmanna Cmek are of pates t present im-

-portanca, ~ls they ham been wholly srweyd and are -fly ac-ible to the mrrin line of the milroad. By the present milroad route the mouth of Hmeama Creek ia about 364 mil- from the coastal terminus at Seward and about 106 d e ~ fmm the inland terminus st F~irbmkn.

The c o d lands of the Nemna coal field that have been o f f e d for h i n g are embraced In T. 11 S., Rs. 5 , 6 , and 7 W., and T. 12 S., R. 7 W. of the Fairbanks meridian and are the moat accessible and moat - immediately minable of the surveyed lands of the field, which include p a r h o f T . 9 S . , R s . 5 , 6 , a n d 7 W . ; T . I O S . , R . 6 W . ; T . l l S . , Rs.5,6,tbnd7W.;zmdTT12S,,R.7W, (SeePLXI,)

The climate of the Nemm c o d fidd is in general tbrt'of the more mountainous part af the Yukon baain. The ahort, hot.summers contrast st-y with the long, cold wintgm. The precipitation in the coal fidd is very light compared with that on the comt, but

[ ie probably aoderably greater than that at Fairbmk~. The sum- mer Iraixlfdl consists largely.of iolent showers. The modall is light. The timber is chiefly spruce, birch, and popztErI which exbnd up to

At least twelve CX)B~ beda a m of workable thickness, and six or mom measure over 20 feet, No geographic or stratigraphic variation in the char- acter of the ooal waa notedm The analyses given on pagm 8-9 abow that the cod is a b i t e of good grade, of about the same quality as that of Cook Lnles.

The cod in the Nenana field will pmbnbly st h t be mined by drifta or dopee rae fmm outcrop of clod on the sidm of the. d e y m or by stripping, The abundmw of easily mmmible -1 and the moderate size of the prospective markets make it certain that deep mining will not be necessary for many yaws.

The mst fammble site for stripping is on the 26.foot bed in block 8, set-35, T. 11 S., R. 7 W., about 5 mil= above the mouth of Hmanna h k . A moderste amount of coal may perhaps be cheaply mined by stripping in blocks 2 andl3, m. 5, T. 12 S., R. 7 W., a lit& o ~ e r a mile above the mouth of Aoaeenns Creek, and perhaps at other localities.

The cod beds have been extemimely burned in many parts of the field, wpmially in T. 9. S., R. 6 W., where only about half a doeen unburned outcbp~ were observed. The burning began prior tu the deposition of the thick Plekhne gr&mIs and atiU continu&. The depth of the budng is not known, but ag burned outcrops are more numerous in the less dismted than in the deeply dissected mas the burning is probably surfiddm The burning makm the value of large morn problmatia and indioatm the danger of h s in the miom.

Extensive slumping was noted on many hillaides. In soma p l a m acres of the surface beds have did bodily for long distmma. Most of the ~1idm.obsewed ham been caused by the mmovd of xhoss by forest k a . Thie removal allows thecpund to thaw and permits the surface waters to soften the deys that form a large part of the coal-bearing strata. Some slides have been c a u d 'by the burning of large cod beds that had supported the surface atrata. 'Phe marked tendency to slump ahou1d be carefully ponsidemd not only in under- ground mining but in surfme operations, such aa the stripping of coal beds, grading, and the removal of fomst~ and moss. The cod will prribably be ueed as locomotive fuel on the Qoaern-

ment mihad, for generating power and for thawing st the mines in Tanma Valley, aa domestie fuel in Tanma Vdey, ind as fuel on Tanana River boetts and posajbly- on some of the Yhkola ateamem. Nenana cad, rather than the better and nearer Mrlatmueka coal, should, if pmaible, be used on the greater part of the railroad, becauee the heavy freight traffic will be northbornti, and the southhund emptim will be a d a b l e for hauling coal.

MYIINLNO CONDITTONB.

There i~ undoubtsdly a large amount of coal in thin township, much of which is above the general drainage love1 and can be mined with- out shafts from openhga situated on the larger creeks.

The ma1 in SICS. 18,19,30, m d 31 and in tho western park. of 8.ecs. 20 gad 29 ia in the drainage basin of Roseanna Creek azld wiJJ find its na,turd outlet over s branch railroad extendmg up the creek from Nenann River. Thm is, bowever, so large a quantity of easily

. m i b l e cod in the Power part of the vday of Hoseaana Creek that probably no such branch will be built into this township for many 7-. *

The coal of the mt of the tmmhip i8 in the drainage bagin of T o b t h h Creek, which is t r i b u e to Tmana River, and will find ita aatural outlet over an independent railroad up the Totatlanika. Srrch a r d a d will not be built for a great many yeam, unless other indua~es than ooal mininp. require it.

I t i probable that the placer mines of T o h t l d a Creek ttnd ib tributaries will require a small amount of cod, some of which may be

t I obtained in this tO~r11~hip. A Iittle coal has already been mined for

this purpose in sac. 8.

1 BTATUB OF COAL JAXD.

Tha coal of thb township is m ~ ~ a m t a from the prwnt mmkete h d from the pmpoeed railroad that there will probably be no demand for letwe, except possibly for a small mine, pruducing annually not more than several hundred tons, to supply the local placer minera.

The coal lands of the larger part of this township have therefore not beaa didded into leasing units but are to be held in their present etntw until there in a call for the panting of lwes or of Id mining ?emits.

This tuwmhip contains a moderately large amount of coal that ia a b ~ e genmal drainage level and ao situated a9 to be . e d y mined, and a larger amount that wil l be available by s h d k The most awmsiile c o d beds are boas which crop out in the hill. east of Cali- fornia Creek in the E. * m. 27 m d on Marguerite and E m m a meeke in -. 32 and 33. The coal beds that yidd the smuts in the SE. + sec. 16 are probably thick and m ~ i b l e and may yield a fairly large tamage. Smdl mines could also be opened e d y on the outrropa dong McAdam and Bonanza creeb. The best sitm for deep mining csn be determined only by specid investigations, probably supple \

rnented by drilling. Present information auggest~ that one of the moat fa~orable sitee for deep mining may ba near the junction of Bonanza and California creeks. In the southwsstern part of tha township (seca. 16 to 23, and 28 to

As there is no present or assured local market or tmqmrtation for the coal of thie township, the coal Ian& of the township h v e not been divided into lemfng units, but are to be held in their present etat~ia till there ia a c d for leases ar for local minirig pimite. .

M I m Q coNf,moh's. In the muth half of this township the coal is well expsed in the

deep valleys of Hoseanna Creek and its tributaries, which have cut ahmt to the base of the nearly horizontal coal-bring mks. Consequently the coal of the south Id of the -hip may be mined from biUside drifta. The mining units should be laid out with refemnee to the topography, each interstmtm area constituting a natural mining unit, The mine should be so situated a9 to mum n a t d draiiqe and d o m - p d e hadage of the loaded mine c m .

The north half of the t o d p , which is drained by Marguerite h k , is not deeply d h c h d , and the amount of cod above drain- age level in this half is small. For extensive - in this part of the towmhip shafts wia probably be necessary.

The coal-bearing rocks of tbis to-p occur in a thin plate on the . north slope of the vdIey of Rex h k . A s no mtud oumps of coal

beds were seen hem, if is impoa~ible to &mate the amount of cod. Probably, however, only a few bgds am present, iLnd these lie near the surface. This coal can best be mined in small, simple operations.

W r n R T A T I O N .

The ma1 of this township be bmght to the present markets only by a railroad along Rex, California, and TO^^^ creeks. Such a railroad would be at least 35 miles long (ta Tananlt River) and will probably not be constructed in the near future.

+ 'Themh no available evidencm c o n d g the distance to which coal .exfends h e a t h the grawls, except that on the northern

margin of thia grave.1 area, in T. 10 S., R. 7 w., the schkh a d not the c d b a i u g mk~ emerge from heneath the gramls.

Neithk is there m p evidence concerning the depth fo 'the ma1 in &me atem where it may be p m n t undm the g r a d . The n d d dip of 15' if continued would csrry the coal down st s rate of about 1,400 feet to the mile benmth the gravela, which m s t least 2,000 feet thick. The amount of dip mag. incream or may dimhkh beneath the gravels, and the direction of the dip may hold

- mrthwaid or may be refresed. On the em- edge of the gravel m a in T. I1 S. ,R. 6 W., and T. 10 S., R. 6 W.,revenaIs of dip and other a h c t n r d &mities were observed. 'It is coneegumtly unaafe h assume &st the men of minable coal

includee mything more thm the area of actuat me1 outcrop, with s narrow dditional zone along the southern margin of the gravels. For purposes of land classification it was w m e d that only those grad+overed areas lying within half a mile of outcrop of coal- bearing rocks are probable coal land. Csntious inmtom may wall regard even tb assumption as undercomernative.

The coal beds we well exposed in the desp gulchee of most of the creeke flowing southward into Hoieanne Creck. The moat favorable dke for immediate mining am localitice where tho J8rgr?r cod beds mom thase cmka, and the natural mining unite me the inkmtream -88.

A h g e mount of coal can be won by drift &rig from o p n h q y on the northern tributtrriea of Roaertnna Creek. It is likcly that a considerable m o u n t of cod, possibly s large proportion of that lor which there will; be a demmd in the immediate future, aan be mined by stripping. A favorable sito for a tripping is on the 20-foot bed (A) in the north bank of Hosema Creek in the S. 3. NE. + and the N. +

! SE. 4 sec. 35. The thickness of the coal, ita position on the edge of the meek, and the compsretively large m e with thin overburden are the favorable featurea for open M g at this locality.

TRARBPORTATION. , AU the known coal in T. 11 S., R. 7 W., is on Hoaeanna Creek or

its tibutariea; sand will be ~ m i l p sbccaeaible from a brmch rdroad extending up the creek. The part of this p r o m branch within thk ~~p will all be within 6 miles of the main railroad line on Nsnana Riser.
