ALTITUDE: 1689m
LENGTH: 1968m
DEPTH: -456m


LOCATION:

At the bottom of a large inclined depression 275m below the Beges track. A cairn by the road marks the depression.


ENTRANCE:

The gaping hole of the entrance shaft is easily distinguished amongst the flat, heather covered limestone. The letters 'LUSS 3.2' written in red paint at the head of the shaft readily identify the cave as Fallen Bear Hole.

DESCRIPTION:

The entrance is an elongated hole, 10m x 12m, opening up to a 79m pitch, landing on a snow and rock cone.  The pitch can be rigged to rebelays at -10m, -26m, -42m using a 100m rope. 
 
Heading east from the main chamber, a crumbly phreatic passage is entered, containing the skeleton of the ‘fallen bear’.  At the end of the passage is a pitch of 13m. Heading back under the pitch head leads to a short ascending ramp (free climbable) and a small breakdown chamber. On the way a small down climb leads to a short continuation, but it does not go (not surveyed).
Back in the small breakdown chamber, the way on is under an obvious large boulder, which leads directly onto the 50m pitch series. This comprises of a steep ramp, split by a breakdown chamber, to a stal ledge and a short vertical pitch. At the bottom of this pitch is a short crumbly passage leading directly to El Caos, via an awkward maneuver.
Part way down the vertical pitch is a parallel shaft, accessed by passing between some stal. This parallel shaft is 12m to a floor, with walking passage to a large clean aven. A further short pitch leads into a meander back under the original pitch, no way on (not surveyed).

El Caos
The 50m pitch lands in ‘El Caos’, a large ramp descending at 45 degrees, full of lose boulders and collapse, that descends down for approx. 300m over several free climbs and scree slope traverses.  There are a number of potential high-level leads within this area.
At the end of the ramp there is s small squeeze between boulders and then a climb down (-320m).  Possible continuation?
About 60m back before the end of ‘El Caos’ a right-hand passage descends between boulders for another 80m, before the roof rises and a ramp ascends to the top of a 27m pitch.  
There is an alternative route via pitches of 8m, 8m, 15m, 10m and P15 to this point.  The stream is met at various points and disappears down narrow rifts.
The bottom of the pitch leads to more boulders and a further ramp down to a chamber with a stream way. Following this leads to the head of a 32m pitch, (possible closer to 50m?)
Opposite the pitch head is a large window with a mender/shaft heading away from the rest of the cave.
At the bottom, the water can be followed down a long meander before disappearing at the bottom (-456m).
Note: conversations and notes from Spanish cavers suggest that either the end is a low crawl in water, that requires neoprene (and could maybe be passed) or a this has been passed and leads to a 40m.  No other descriptions beyond this point are known.
 
LUSS 70’s Series
From the entrance pitch, the passage heading west, descends down the main chamber, before narrowing and widening into another chamber. A small hole (approx. 18m) can be avoided on the left and then a climb down reaches the bottom of the chamber.  At the lowest point, a pitch of 32m leads to a ramp and then another pitch of 27m.  (altitude of -196m)
