Ndichishandisa mienzaniso yakatorwa mumashoko acho ndipei rondedzero yemamiriro ezvinhu okutanga anowanikwa muYellowstone National Park.
Context:Yellowstone National Park inzvimbo yeAmerica yenyika inowanikwa kumadokero kweUnited States, kunyanya kuchamhembe kwakadziva kumadokero kweWyoming uye inosvika kuMontana neIdaho. Yakagadzwa ne42nd U.S. Congress neYellowstone National Park Protection Act uye yakasainwa kuva mutemo neMutungamiri Ulysses S. Grant musi waMarch 1, 1872. Yellowstone yakanga iri paki yenyika yokutanga muU.S. uye inorangarirwawo zvikuru kuva paki yenyika yokutanga munyika. Paki yacho inozivikanwa nokuda kwemhuka dzayo dzomusango uye zvinhu zvayo zvakawanda zvinopisa pasi, zvikurukuru Old Faithful geyser, chimwe chezvinhu zvayo zvakakurumbira. Kunyange zvazvo ichimiririra marudzi akawanda ezvisikwa zvipenyu, sango repamusoro pemakomo ndiro rakawanda zvikuru. Icho chikamu cheSouth Central Rockies masango ecoregion.  Nepo maIndia ekuAmerica akararama mudunhu reYellowstone kweanenge makore 11,000, kunze kwekushanyirwa nevarume vemumakomo mukati mekutanga-kusvika-pakati pezana ramakore rechi19, kuongorora kwakarongeka hakuna kutanga kusvika mukupera kwema1860. Kutarisirwa nekutarisirwa kwepaki pakutanga kwakawira pasi pesimba reU.S. Department of the Interior, Secretary weMukati wekutanga kutarisira paki ari Columbus Delano. Zvisinei, U.S. Army pakupedzisira yakapiwa basa rokutarisira kutarisirwa kweYellowstone kwemakore 30 pakati pa1886 na1916. Muna 1917, kutarisirwa kwepaki kwakaendeswa kuNational Park Service, iyo yakanga yagadzirwa gore rakapfuura. Mazana ezvivako akavakwa uye anochengetedzwa nokuda kwokukosha kwawo kwokuvaka uye kwenhau, uye vanzveri vakaongorora nzvimbo dzinopfuura chiuru dzokuchera matongo.  Yellowstone National Park inotambanudza nharaunda ye3,468.4 sq mi (8,983 km2), inosanganisira makungwa, makoronga, nzizi, uye makomo. Gungwa reYellowstone nderimwe remakungwa makuru ari munzvimbo dzakakwirira muNorth America uye riri pamusoro peYellowstone Caldera, gomo guru rinoputika riri munyika yacho. Caldera inoonekwa segomo rinoputika risingaiti basa. Yakaputika nesimba guru kanoverengeka mumakore mamiriyoni maviri apfuura. Inopfuura hafu yemakomo anoputika munyika yose uye nzvimbo dzinoputika mvura dziri muYellowstone, dzinosimbiswa nokuita uku kwemakomo kunopfuurira. Mvura inonaya uye matombo anobva pakuputika kwegomo rinoputika zvinofukidza chikamu chikuru chenyika yeYellowstone. Paki yacho ndiyo musimboti weGreater Yellowstone Ecosystem, yakakura kupfuura dzose yasara isingachinji-chinji munharaunda yeNorthern temperate yePasi. Muna 1978, Yellowstone yakatumidzwa kuti UNESCO World Heritage Site.  Mazana emarudzi emhuka dzinoyamwisa, shiri, hove, zvinokambaira, uye mhuka dzinogara mumvura nepanyika zvakanyorwa, kubatanidza dzinoverengeka dziri mungozi kana kuti dzakatyisidzirwa. Masango makuru nemasango ane miti yakasiyana nemimwe. Yellowstone Park ndiyo nzvimbo huru, uye yakakurumbira zvikuru ye megafauna muUnited States. Mabheya, mapuma, mhumhi, uye mapoka emabhisoni nemapere anorarama akasununguka anogara mupaki iyi. Boka rebhisoni reYellowstone Park ndiro boka rebhisoni rekare kupfuura ose uye rakakura kupfuura ose muUnited States. Moto wemusango unoitika mupaki gore negore; mumoto mukuru wemusango wa1988, inenge chikamu chimwe muzvitatu chepaki chakapiswa. Yellowstone ine mikana yakawanda yokuzorora, kubatanidza kufamba netsoka, kudzika musasa, kukwasva igwa, kubata hove, uye kuona nzvimbo. Migwagwa yakavakwa zvakanaka inoita kuti munhu asvike pedyo nenzvimbo dzinopisa zvikuru uyewo dzimwe dzenyanza nemapopoma. Munguva yechando, vashanyi vanowanzosvika mupaki vachishandisa makombi kana kuti motokari dzinotakuriswa chando.
Kazhinji inorangarirwa kuva paki yenyika yokutanga munyika, Yellowstone National Park ine ukuru hunokosha, inofukidza mativi eWyoming, Montana, uye Idaho, uye inoshanda senzvimbo huru dzakasara dzinosvika-dzisina kukanganiswa. Iyi paki inokwanisa kutsigira marudzi mazhinji emhuka dzesango dzinosanganisira Grizzly bere, cougars, mhumhi, mbudzi dzemakomo, mapoka akasununguka emabhisoni nemapere, pamwe nemarudzi mazhinji eshiri nehove, nekuda kwekusiyana kwenzvimbo dzekugara. Masango nemasango ndiwo anonyanya kuwanikwa mune dzimwe nzvimbo dzepaki yacho, asi dzimwe dzinopa maonero akasiyana zvachose enzvimbo dzine makomo, makungwa, uye minda ine makomo. Zvimwe zvezvinhu zvakatanhamara zvepaki yacho ndezvemvura inonaya uye mvura inopisa. Kutaura idi, Yellowstone musha weinopfuura hafu yezvinhu zvenyika zvakadai seizvi. Izvi imhaka yokuti paki yose yakavakirwa paYellowstone Caldera, gomo guru rinoputika riri muAfrica.
