The young age of relict glacial forms in our highest mountains /not older than LGM age, 24-18 ka BP/, and the almost complete absence of traces of ancient glacial landscape, supports the suggestion for the relatively young intensive uplift of Rhodope massif (very strong during the second half of the Pleistocene).

It comprises the highly weathered carbonate bedrock which is located immediately beneath the surface or is exposed at the surface. Porosity and permeability are higher near the surface than they are at depth, and consequently, after recharge percolating rainwater is detained near the base of the epikarst, the detention ponding producing an epikarstic aquifer. The present article makes a summary of the essence of epikast and focuses especially on the factors that determine its formation, present state and development. Въведение Карстовият процес е сред основните и най-важни геоморфоложки процеси на Земята. На окарстяване са подложени около 20% от повърхността на нашата планета. Уникалното в карстовия процес е неговото развитие в дълбочина, което е свързано с формиране както на повърхностни, така и на подземни форми. Докато пещерите и свързаните с тях форми са обект на доста голямо внимание от страна на учените, то процесите, които стават на повърхността в окарстените територии, или в близост до нея, са по-слабо изучавани. В същото време състоянието на повърхностните части на карстовите масиви е важно както от екологична, така и от стопанска гледна точка.
