|Along the San Mateo-coastline: 37.36872, -122.40683|
But it's also a place where people have tried to build things for quite a long time. It's a tough environment. When there aren't earthquakes, the soil gives away. When it rains, the mud flows come. In the summertime, this coastline is usually fogged in. Still... it's so beautiful that people keep trying.
I went camping this past weekend with my family near this place on the coast. As you drive along Highway 1, you'll see various attempts that have marked the land with their histories. I spotted this particular anomaly as we drove past and wondered "What is that?"
In the aerial photograph above (taken at lat/long 37.36872, -122.40683 ), you can see Highway 1 on the right, and two linear marks between the road and the edge of the sea cliff. Here, the ocean is around 160 feet (48 meters) below the cliff edge, so what we see here is a fairly flat piece of ground suspended high in the sky.. with two mysterious construction remnants left on the surface.
Your question for today:
1. What is (was) the reason for the long rectangle on the left near the cliff? When was it built? When was it destroyed?
2. (Extra credit) If you can figure out the first one, then the second one should be easy too: Same question--what's the long linear feature between Highway 1 and the rectangle? When was IT made? And when was IT destroyed?
You'll find that you need to take rather different research approaches to find the answers to both of these questions. But I know you can do it! You're SearchResearchers!
Be sure to let us know HOW you found the answers (so we can all learn from your successful search path) and HOW LONG it took you to work it out.
