What's with that boulder? It looks like a good shove good take out Alex and roll it all down the hillside.

That boulder is our anchor! Alex tied a few ropes around it. It would have to be a pretty good shove indeed, as precarious as it looks. Granite is around 2700 kg / m^3. Let's assume it is a sphere of radius 1m, the volume would be 4/3 pi r ^ 3 = 4.2 m ^ 3, or around 11,000 kg, or about 25,000 pounds. Better question is how in the world did it get there??
