. This excavation lasted until 2000, and was focused on determining the age of the materials, finding out if similar items could be found elsewhere in Europe, and reconstructing the prehistoric surroundings. The results were presented in a 2002 report. Work was interrupted in 2001, because of the risk that the cave was about to collapse, in part as a result of the excavation itself, but the cave was stabilized in 2002, and a protecting

Work began again later that year, and in the following years, excavations took place in the early summer each year.


Findings

After eight summers of digging, about 200 artifacts, some 600 pieces of strike waste, scrapers and bolt stone, and heated stones from an open fire have been found. The objects are made of various materials, including

The ground in Susiluola consists of at least eight layers, of which the fourth and the fifth are the geologically and archeologically most interesting.

Criticism

There is disagreement as to whether Neanderthals actually settled in the cave. In 2006, Joakim Donner, Professor Emeritus in Geology and Paleontology, published in the journal criticisms of the idea that the materials found in the cave were created by humans. Donner claims not only that stones from Susiluola are not similar to Neanderthal objects found in France, but also that the cave was located under water during the time period in question, and that there is no proof that fire was made there. Hans-Peter Schulz of the National Board of Antiquities has defended the findings, saying that it is very possible that the cave was situated above water level at the time, and that soot from the fireplace that has been found is over 40,000 years old and cannot have come from outside the cave. The justification that the pieces of stone found in the cave are actually products of human beings is, according to Schulz, that the objects have been exposed to a rapid and aimed blow, leaving a surface that does not look similar to one that has been exposed to exogenous processes, but does resemble those of man-made objects from the Paleolithic found in central Europe. The debate was widely reported in the press. In 2007, several critical papers from Finnish geologists and archaeologists were published in the archaeological journal ''Fennoscandia archaeologica'' (vol. XXIV). The authors in question were not convinced that the finds and features found in the cave are man-made. Debate continued until 2016, after which the site fell out of mainstream academic discussion.
