Nhanho iyi ichave iri kumaodzanyemba kwakadziva kumabvazuva kweWyoming, muUnited States, munzvimbo yakawanikwa akawanda emakorota, ese akaumbwa makore mazana maviri nemakumi masere apfuura. Muchinyorwa chazvino chakabudiswa mu 'Geological Society of America Bulletin' (GSA Bulletin) boka revatsvakurudzi vekuGermany neNorth America, vachitungamirirwa naThomas Kenkmann, wekuGermany University yeFreiburg, vakatsanangura kuti makoronga aya, ari pakati pe280 ne10 metres dhayamita, ichasikwa mushure mekuita kwemeteorite makiromita zana kure, kutanga nhamba huru yematombo kuburikidza nenzvimbo, iyo yakadzoka mushure mekuwira pasi mumusasa. Apo a
dombo remuchadenga rinodhumhana nepuraneti kana mwedzi, zvinhu zvinobviswa kubva pamusoro zvakagadzira gomba. Mabhuroko makuru echinhu ichocho anogona kugadzira 'makomba' awo ega pasi.
"Makwara -anotsanangura KenKmann- anoratidza kwainobva kumwe chete uye kuti ma crater akaumbwa sei nemabhuroko akabudiswa kubva mugomba guru rekutanga. Makorokoto echipiri akatenderedza makorokoto makuru anozivikanwa zvikuru kune mamwe mapuraneti nemwedzi, asi haana kumbobvira awanikwa paNyika." Pasina imwe nguva, Shanduko yeChina 4 mission yakaongorora dunhu riri kudivi reMwedzi uko chiitiko ichi chakaonekwa munzvimbo ina 'source craters': Finsen, Von Kármán L, Von Kármán L' neAntoniadi.
Kerkmann nechikwata chake vakatoona 31 sekondari crater muWyoming izvo zvinosiya pasina kupokana, asi vakawana mamwe makumi matanhatu avanga vasati vakwanisa kuenderana negomba guru.
Nyaya yakatanga muna 2018, apo Kenkmann nevamwe vake vakaongorora akateedzana makorokoto akatenderedza Douglas, Wyoming. Panguva iyoyo, taifunga kuti ose akanga akaumbwa nezvimedu zvakasiyana zvenzvimbo imwe chete yepurogiramu yakanga yaputsika mumhepo. Asi akazowana mamwe mapoka gumi nemaviri ezera rimwe chete, akazara munzvimbo yese.
Maererano neongororo iyi, matombo anoumba masecondary craters anofanirwa kunge aive pakati pemamita mana ne4 muhupamhi, uye akawira pasi nekumhanya kuri pakati pe8 ne2.520 km/h. Kuwedzeredzwa kwematanho evanokanganisa pamusoro pezvinobvamo zvinoratidza kuti iro rekutanga, risati raonekwa gomba rinosvika pakati pemuganhu weWyoming-Nebraska kuchamhembe kweCheyenne.
Sekureva kwechikwata, crater iyi ingangove iri pakati pemakiromita makumi mashanu ne50 yakafara, uye yakagadzirwa nemushonga uri pakati pemakiromita mana ne65 muhupamhi. Maererano nevatsvakurudzi, gomba guru rinogona kunge rakavigwa mamwe makiromita mashoma kubva pamatope akaungana mushure menguva yekukanganisa. Huwandu hwakaenzana hwemashanga, zvisinei, huchakungurusa nekufumura magomba echipiri apo, gare gare, Sierra Rocosa inosimudzwa.
Zvisineyi, Kenkmann anotenda kuti gomba guru iri rinogona kuwanikwa kuburikidza nekudzidza magineti uye magineti enzvimbo yedunhu kana paine kusanzwisisika kunoratidza kuvepo kwaro.
