Otkrivena je 1973. godine prilikom kopanja i miniranja kamena koji je koristio za proizvodnju vapna, a godinu dana kasnije za\u0161ti\u0107ena je kao geomorfolo\u0161ki spomenik prirode. Trideset godina kasnije, prilikom radova na pro\u0161irenju prostora za prihvat posjetitelja, otkriven je ulaz u drugu \u0161pilju, poznatu kao \u201eNova Grgosova \u0161pilja\u201c. \u0160pilja je od 2008. godine ure\u0111ena za posjete.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-vz-jquery” bg_image_new=”id^11429|url^https:\/\/zeleni-prsten.hr\/portal\/wp-content\/uploads\/2022\/02\/Fotografija-2.jpg|caption^null|alt^null|title^Fotografija 2|description^null”][vc_column width=”1\/3″ css=”.vc_custom_1616094504001{background-color: rgba(0,0,0,0.6) !important;*background-color: rgb(0,0,0) !important;}”][vc_column_text]Do sada su analizirane dvije sige iz nove Grgosove \u0161pilje, njihova starost i klimatski uvjeti koji su nekad vladali. Jedan stalaktit po\u010deo je rasti prije 10 500 godina, a prestao je rasti prije oko 2 300 godina. U razdoblju rasta rastao je brzinom od 0,8 do 1 cm u 100 godina ili 0,08 do 0,1 mm godi\u0161nje. Najstariji dio drugog stalagmita star je oko 40 000 godina s promjenom brzine rasta od 0,1 do 1 cm u 100 godina.<\/span>[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][\/vc_column][vc_column width=”1\/3″][\/vc_column][\/vc_row][vc_row full_width=”stretch_row”][vc_column][vc_column_text css=”.vc_custom_1646188821245{padding-top: 2rem !important;padding-bottom: 3rem !important;}”]<\/p>\n

Prirodne vrijednosti<\/h2>\n

Obje \u0161pije su relativno malih dimenzija ali zbog izuzetnog bogatstva \u0161piljskim ukrasima predstavljaju turisti\u010dku atrakciju i prepoznatljiv su dio geoba\u0161tine Zagreba\u010dke \u017eupanije. Ukupna duljina stare spilja je 52 m, a dubina u odnosu na razinu ulaza je 19m. Zapremnina spilje 1750m3. Ukupna duljina nove spilje 97 m, a dubina 14 m.<\/p>\n

Prema vrlo debelim sigastim nakupinama i stalagmitima na tlu mogu\u0107e je zaklju\u010diti da \u0161pilja ima relativno veliku starost, dok nam mno\u0161tvo tankih stalaktita na stropu ukazuje na jo\u0161 uvijek postoje\u0107i proces stvaranja i oblikovanja prostora \u0161pilje.<\/p>\n

Posebna vrijednost \u0161pilja su brojne sige razli\u010ditih vrsta. Grgosovu spilju krase cjev\u010dice ili makaroni, ekscentir\u010dne sige te zavjese ili draperije. Cjev\u010dice su tanki stalaktiti jednoli\u010dne debljine a helaktiti ili ekscentir\u010dne sige stalaktiti nepravilnog oblika koji izgledaju kao da prkose djelovanju sila te\u017ee. Zavjese ili draperije su lijepe sige koje sa stropa vise poput naborane tkanine i nastaju kada se kapljice polako slijevaju po kosim zidovima. Svaka nova kap ostavlja trag i tako zavjese postaju sve dulje i dulje.<\/p>\n

Prema analizi siga iz \u0161pilje do\u0161lo se do saznanja da se sastoji od 95% kalcijevog karbonata i 5% alumosilikata. Sige u spilji su razli\u010ditih boja: bijele, blijedo – \u017eute, \u017eute, naran\u010daste i sme\u0111e. Obojenost siga ovisi o mineralnim primjesama, o tlu iznad spilje, biljnom pokrovu i o stanju okoli\u0161a.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-vz-jquery” bg_image_new=”id^11431|url^https:\/\/zeleni-prsten.hr\/portal\/wp-content\/uploads\/2022\/02\/Fotografija-3.jpg|caption^null|alt^null|title^Fotografija 3|description^null”][vc_column width=”1\/3″ css=”.vc_custom_1616094504001{background-color: rgba(0,0,0,0.6) !important;*background-color: rgb(0,0,0) !important;}”]

Dvojenoge<\/h2>\n

Dvojenoge ljudi poznaju pod nazivom stonoge. Nedavno je u Australiji opisana podzemna vrsta s najvi\u0161e nogu na svijetu, \u010dak 1306. Kod dvojenoga je zanimljivo da im se broj nogu mijenja kroz \u017eivot. Kako rastu i presvla\u010de se, tako im se pove\u0107ava broj koluti\u0107a od kojih im je gra\u0111eno tijelo, te automatski raste i broj nogu. Ve\u0107ina \u0161piljskih vrsta u Hrvatskoj su endemi.[\/vc_column_text]

Skokuni<\/h2>\n

Skokuni su sitni beskralje\u017enjaci koji su hrvatsko ime dobili po zanimljivom pona\u0161anju. Kada osje\u0107aju da su u opasnosti, naglo lupe po tlu organom koji se zove furka i pomo\u0107u njega mogu sko\u010diti nekoliko stotina puta dalje od svoje veli\u010dine. Jedini bolji skaka\u010di na svijetu su buhe. U Hrvatskoj je zabilje\u017eeno 35 \u0161piljskih vrsta skokuna.[\/vc_column_text]
