What Does "Bedrock" Actually Mean Under Jerusalem?

When you hear "we hit bedrock," it sounds like a universal floor of solid stone. But under Jerusalem, the reality is far more layered—literally. This episode unpacks what engineers actually mean by bedrock, why the Meleke limestone that built the Temple Mount isn't strong enough for a modern high-rise, and how the depth to competent rock can shift from zero to thirty meters in just two blocks. If you've ever wondered what's really under your feet in this city, or why those excavation hammers sound different from week to week, this one's for you.
