CRACK CLIMBING

Although this crack is too wide for a good finger lock, its also too shallow to get a decent hand jam. But deeper in there's a thinner crack!
Slide your hand in deeper, slot those fingers, and this awkward crack turns into a great finger lock!
Check out how the index finger is resting on a slight "ledge" on the right side of the crack. Counter pressure with the knuckles keeps the fingers pressed on the ledge for a secure open grip even though the "ledge" is pretty thin and sloping. Similarly, hidden vertical ledges inside cracks can turn into great sidepulls.
