Speleo divers from Triton-AST started the explration of submerged galleries of Lazareva pećina.

Expecting a hydrological minimum, the explorers found this summer a flow of 200 l/s. 222m of new galleries was added to the survey.

Aleksandar Milosavljevic, the diver who first divedin Rakin ponor in 2000, reported that the blockage at -13m did exist also in 2000, but he was able to squeze through, reaching finally -29m (the gallery still goes on). This dispersed the doubts about the correct depth of Rakin ponor (256 + 29)

On August 10th, SAIS cavers surveyed some 100m of new passages and pushed the cave over 9 km. The new length is 9086 meters.

Joint explorations of ASAK and Bradan in January pushed the cave well into the 8th kilometer! It is 8689 meters long since January 20th.

After 7 years, speleodivers from SOB-a and from Poland dived again at the bottom of the deepest cave in Serbia, Rakin ponor. In 2000, the diving depth was 29m, but in 2007, an impassable blockage made of accummulated debris was reached at only 13m... It is still unclear how so massive blockage could get there, but there are no doubts that Rakin ponor is no more the deepest, since it ends at 256 + 13 = 269m

An international caving camp "Technical impromvement in speleology" was held in Zlot, in August. During the camp Lazareva pećina was explored further, and 1123m new galleries were surveyed. Total length of the longest cave in Serbia is now almost eight kilometers. When konwn, but not yet surveyed galleries are summed, the estimated length reaches 10.5 km.

Cavers from SOB resurveyed the cave, using better instruments than before (brunton compass, Leica Disto, laser inclinometer). The calculated depth was only 241m. When old and new surveys are compared going up from the bottom of the cave, there are no major differences. The problem of choice of the "zero point" of the cave arose once again (the vertical entrance is at the bottom of an open air extremely steep doline - where should one start the survey?). Analysis will follow, but it is obvious that the official depth will not remain -276m.
