Gurio_Lamanna

Gurio Lamanna (also incorrectly called Gurlamanna) is a doline shaped like a coat of arms located in the Murge plateau and falling into Gravina in Puglia's territory, on the border with Altamura, Apulia, southern Italy. It is "one of the largest karst landforms of the Murge plateau" and it is located very close to other two dolines, namely Pulicchio di Gravina and Tre Paduli. Depending on the type of geomorphologic classification employed and the author who suggested it, the karst landform can be defined either a doline or a "karst basin" (Italian: bacino carsico). It is traditionally called "karst basin", following the suggestion of Carmelo Colamonico, who first studied the doline and saw in its large size and shallow depth a good reason to distinguish it from a normal doline. The definition of "karst basin", used by Carmelo Colamonico, has been introduced by Renato Biasutti. Carmelo Colamonico stated that Gurio Lamanna is "one of the best examples of karst basin in the Murge plateau".
