Avenc dels Arqueòlegs

In a small depression located on one side of the avenc Gran de les Alzines, we find the small entrance of 0'87X0'47 metres. A 3'50-metre shaft leads us to a small sloping chamber, where to reach the next shaft of -35 metres it is necessary to get through a narrow squeeze of 0'50X0'55 metres. The shaft has an average diameter that does not reach one metre. At -15 and -30 metres, we find two niches with no continuation. At the base of the shaft it widens a little and on one side a narrow descending fissure leads us to a small chamber where we find the point of maximum depth at -46 metres.

To reach the next shaft of -35 metres it is necessary to get through a narrow squeeze of 0'50X0'55 metres, where a light air current blows. The descent presents considerable difficulty, especially with the sharp protrusions of the walls. At the base of the shaft, a narrow descending fissure leads us to a small chamber where we find the point of maximum depth at -46 metres, where the only possibility of continuation is a small blowing squeeze pending digging.
