The first hole is triangular with sandy-floored passage leading to 2 things: firstly, a small slot in the floor where rocks fall for ~2 sec, and secondly a climb/squeeze over/under a large rock to a rocky floor, roof ~15 feet here. It appears that a narrow canyon is filled with rocks for ~10ft - maybe after that it could be descended.Further round are 2 holes together. Lower of the two is full of rocks. Nearer is steeply sloping hole (sounds dead).
