evidence: Klek is a mountain in north-western Croatia, near Ogulin in Karlovac County. It is the easternmost mountain of the Velika Kapela range of the Dinaric Alps. [...] Geography and geology [edit]Klek is positioned as a prominent ridge on the eastern tips of Velika Kapela, and its slopes descend toward Ogulin and the valley of Dobra. The peaks are steep and rocky, and there are two most important ones, Klečice or Mali Klek (1058 m), and Veliki Klek (or just Klek, 1182 m), with its prominent vertical 200 meters high "southern rock". [...] The climate is mountain with heavy rainfall, which encourages the formation of seeping and torrent streams that gather in Klek's ravine (Klečka draga in Croatian) or Peras' gulch (Perasov jarak in Croatian). Behind Peras' gulch on the northern slope of Klek there is also a ruin of the old Frankopan castle Vitunj, above a village named the same.
