Lub Meteor Crater nyob ze ib nrab ntawm Petrified Forest National Park thiab Grand Canyon, 10 mais ntawm lub nroog Winslow nyob rau sab qaum teb Arizona.

Qhov chaw ntawm lub meteorite crater hauv Arizona

Ib zaug dhau los, ntev dhau los (cov kws tshawb fawb xav tias nws yog 27 txhiab xyoo dhau los), ib lub meteorite poob rau thaj av Arizona. Los ntawm cov qauv cosmic, lub hnub qub me me, tsuas yog 40 meters hauv txoj kab uas hla thiab tsuas yog 300 txhiab tons hauv qhov hnyav. Lub meteorite tsoo hauv av, tawg mus rau hauv cov khib nyiab hauv thaj tsam ntawm 5 km thiab tsim ib lub qhov tsua nrog txoj kab uas hla ntawm 1200 meters thiab qhov tob ntawm 175 meters. Nws tau suav hais tias txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tsim, lub meteorite yuav tsum ya ntawm qhov nrawm ntawm 69 txhiab km / h! Qhov kev cuam tshuam tau muaj zog heev uas cov seem ntawm cov meteorite tau pom ntawm qhov deb txog li 10 km! Lub zog ntawm qhov tawg ntawm qhov cuam tshuam yog kwv yees li ntawm 500 kilotons, uas yog 40 npaug ntau dua li qhov tawg ntawm lub foob pob nuclear poob rau Hiroshima.

Lub Arizona Crater (aka Barringer Crater) yog ib qhov loj tshaj plaws thiab zoo tshaj plaws-preserved crater nyob rau hauv lub ntiaj teb no. Cov kws tshawb fawb pom lub qhov tsua tsuas yog thaum pib ntawm lub xyoo pua 20th, thiab cov pab pawg neeg hauv zos Navajo Indian tau paub ntev txog qhov chaw ntawm qhov crater. Cov Khab Khab hu ua crater Devil's Canyon thiab txuam nrog ntau cov lus dab neeg thiab kev coj noj coj ua nrog nws.

Sab laug ntawm lub qhov tsua. Nws tau suav hais tias txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tsim, lub meteorite yuav tsum ya ntawm qhov nrawm ntawm 69 txhiab km / h!

Muaj ob peb zaj dab neeg nthuav qhia txog qhov crater. Yog li kom txog rau thaum lub xyoo pua 20th, cov kws tshawb fawb xav tias craters yog cov volcanic keeb kwm, thiab tsuas yog nyob rau hauv 1902 engineer Daniel Barringer tau hais tias lub crater tuaj yeem tsim los ntawm qhov poob ntawm lub cev xilethi-aus loj. Barringer yuav ib daim av uas lub crater nyob thiab pib excavate, sim nrhiav lub cev ntawm lub meteorite. Cov kev khawb av tau qeeb rau 26 xyoo, thiab Barringer, ntawm chav kawm, tsis pom dab tsi, thiab nrhiav tsis tau dab tsi, vim feem ntau ntawm cov meteorite kub hnyiab tau nyob rau hauv cov huab cua, thiab tag nrho cov uas tseem tshuav tau tawg khiav ri niab nyob ib ncig ntawm lub cheeb tsam. Vim tias tsis muaj pov thawj, Barringer qhov kev xav tias cov craters yog meteor lem tau raug tso tseg thiab tsis nco qab lawm, thiab kev khawb tau raug tso tseg. Tsuas yog ob peb xyoos tom qab ntawd, ib tus kws paub txog ntiaj teb Asmeskas thiab kws tshawb fawb txog hnub qub muaj peev xwm ua pov thawj qhov xwm txheej ntawm Arizona crater.

Qhov chaw ntawm Barringer drilling rig tseem nyob hauv qab ntawm lub qhov tsua. Lawv muaj hnub nyoog 100 xyoo, lawv tau xeb tag nrho, tab sis lawv tseem tshuav nyob rau hauv qhov chaw ua ib lub tsev khaws puav pheej rau kev tsim kho ntawm cov tiam tom ntej. Hmoov tsis zoo, koj tsis tuaj yeem nqis mus rau hauv qab ntawm lub qhov tsua, thiab kuv tau suav nrog nws.

Lub Meteor Crater yog lwm qhov piv txwv ntawm Asmeskas kev npaj ntawm cov chaw keeb kwm. Ib txoj kev zoo coj mus rau sab qab teb mus rau lub qhov tsua ntawm I-40. Lub crater nws tus kheej los ntawm sab zoo li lub tais nrog tsa sawv nyob rau hauv nruab nrab ntawm Arizona suab puam. Lub rampart bordering lub crater nce 40 meters. Nyob rau ntawm ko taw ntawm lub qhov tsua, ntxiv rau qhov chaw nres tsheb, muaj ib lub tsev khaws puav pheej loj, uas nthuav tawm cov duab meteorite, ntau yam duab thiab video ntaub ntawv, ntawv xov xwm thiab phau ntawv. Lawm, muaj cua txias, uas yog ib qho tseem ceeb heev tom qab tshav kub ntawm cov suab puam. Lawm, muaj ib lub khw muag khoom plig. Lawm, muaj zaub mov ceev (lub tsev noj mov Subway nyob rau hauv lub tsev cia puav pheej). Yog tias koj tub nkees dhau mus nce phab ntsa crater, koj tuaj yeem nqa tau yooj yim. Saum toj no, nyob rau ntawm ntug dej hiav txwv, muaj ob peb saib platforms nrog lub rooj ntev zaum thiab telescopes. Pom tau tias, nws tau xav tias cov neeg Asmeskas ib txwm, tau ntaus cov qhaub cij nrog Coca-Cola hauv Subway, yuav qhuas tus crater, xav txog ntawm lub rooj ntev zaum thiab qee zaus ntsia ntawm lub qhov muag.

Daim pib nkag mus rau Meteor Crater raug nqi $ 15, uas yog kim heev. Tab sis raws li nws tau muab tawm tom qab, rau cov nyiaj no, tus qhua tsis tau txais daim pib xwb, tab sis kuj muaj daim coupon luv nqi hauv Subway, uas tso cai rau nws kom tau txais cov qhaub cij dawb thaum yuav ib cocoa. Cov cua sov yog qhov tsis txaus ntseeg, thiab txhua tus neeg nqhis dej, yog li qhov kev pabcuam no tsim nyog heev.

Los ntawm txoj kev, qhov zoo kawg li, Arizona crater tau pom tias zoo ib yam li cov toj roob hauv pes lunar, thiab nws nyob ntawm no uas NASA tau ua kev cob qhia rau txhua tus neeg caij nkoj uas yuav ya mus rau lub hli. Pab pawg tshwj xeeb ntawm Apollo 11 astronauts tau kawm ntawm no, nrog rau Neil Armstrong thiab Edwin Aldrin lawv tus kheej, uas thaum Lub Xya Hli 21, 1969 yog thawj zaug hauv tib neeg keeb kwm los taug kev ntawm lub hli. Vim li no, tus chij Asmeskas tau tsim nyob hauv nruab nrab ntawm lub qhov tsua.

Thaum kuv tab tom tshuaj xyuas lub qhov tsua, tag nrho cov tub rog ntawm tub rog Apache nyoob hoom qav taub hauv cov xim camouflage ya los ntawm qhov chaw nyob rau sab qab teb. Tom qab lub nyoob hoom qav taub, Apaches maj mam thiab imposingly ncig lub crater peb zaug thiab ploj mus rau sab qab teb. Ib feeb tom qab, ib tug ntawm Apaches rov qab, hovered rau ob peb feeb nyob rau hauv nruab nrab ntawm lub funnel, ces tig ib ncig thiab caum tus so ntawm pab pawg neeg tom qab burner.

Zoo, peb tau mus rau hauv lub tsheb thiab mus rau lub Grand Canyon. Thaum dhau los, Irishka pom tus tsiaj coj txawv txawv ntawm lub tsheb hauv qhov chaw nres tsheb, tsis zoo li squirrel tawv nqaij. Txawm li cas los xij, nws tsis tuaj yeem ntes nws - nws tau khiav ceev ceev hauv qhov ntxoov ntxoo ntawm cov tsheb sawv thiab ua tiav nws tus kheej camouflaged.
