In 1992 the 2816m tunnel Kollfjarðartunnilin was opened from Kaldbaksbotnur to Kollafjørður[1] and this is now the main route from Tórshavn to the villages in the north of the island.

[2] A sample of stalagmitic white Mordenite (Na2CaK2)Al2Si10O24·7H2O) from Kaldbaksbotnur was collected by Volker Betz and can be seen at http://www.mindat.org/photo-177823.html[4] Kaldbaksbotnur is referred to in a song Útsetin performed by Teitur Lassen on his 2007 album Káta Hornið.

[5] It is performed in the Faroese language but the extract below (the 3rd and 4th verses out of eight) includes an English translation: eg vendi aftur til ódnarveður vánaligar fløguútgávur eina árliga blokering av Kaldbaksbotni

hampafólk í samkomu sum eru útbúgvin í bíbliu men rodna tá eg syngi um samkynd og nekarar I return to stormy weather bad album releases an annual blockade of Kaldbaksbotnur

decent folk in congregations who have Bible educations but blush when I sing about gays and negros
