Here we are on the southern edge of the Valley of Jezreel. Looking across the valley, we could see Mt. Tabor and Nazareth.
Back in the 9th c. BC, King Ahab constructed a massive system with a 30 meter deep shaft and a 70 meter long tunnel. This tunnel connected the bottom of Ahab's shaft to the spring. Before its construction, Megiddo residents had to leave the city walls in order to get water from the spring. This tunnel was hewn from both ends at the same time (like Hezekiah's Tunnel) and its builders were only one foot off when meeting in the middle.
Jim took us down this tunnel. There were 183 steps down to the spring. I wondered "How in the world will I ever climb back up?!"
