After descending the historic steps 

and the old ladder

through both the keyholes

followed by the narrow ledges 

and following the track around through the ferns,

we could see a massive landslip.

Up close it was clear that the track had totally disappeared 

and what was 200m of vertical cliff was strewn across the tallus slope for well over 100m.

Presumably the recent rains had weighed down the porous sandstone to the point of no return.

The original track was obliterated, the rock and sand still unstable. In time a new track will be made that still hugs the cliff face. In the short term, I’d expect walkers to descend to a safer place to cross the debris and reascend somewhere around the corner.

We traced our steps that day.

The lower route the the Colosseum across the tallus slope that starts at the sign by the 2nd keyhole would remain unchanged.
