why a boulder? why not something lighter - use less power? |
|
|
If you jumped unto anything light it would have not have
sufficient inertia. A boulder is also usually a lumpy object
with many hand and foot holds. Any energy required to
lift up the boulder would be counter-balanced by the
other boulder in the adjacent shaft, to which it would be
connected via an over loop, simultaneously making its way
down. |

I'm thinking polystyrene... |
|
|
I tense, quick-release piton in each hand, and wait for the next rock. I see it rising in the gloom of the shaft. One final check of balance and footing, a deep breath, a scream, and a leap onto the ascending stone. I achieve a secure grip almost instantly, then take a deep breath and let the adrenaline surge wash away. |
|
|
As I reach the next floor, a motion seen from the corner of my eye gives me a bare instant's notice that another rider, similarly equipped, is going to use the same spot I'm in. |

Careful [po], ideas like this never withstand much "Why?". |
