Not to worry... we'll close off the "KML analysis" problem tomorrow. I know a couple of people still wanted to work on it, so I'll write a post with all the answers on Thursday.
And in the meantime, here are a couple of quick Search Challenges to keep you going. Here, the Challenge isn't so much finding an answer, it's really about understanding the question.
1. Vernal Fall in Yosemite National Park (see above) is one of the most beautiful waterfalls in the world. It's also dangerous, as people get too close to edge and slip over the side in a heartbeat. The Challenge here is this: What is the elevation of Vernal Fall?
2. What is the distance to Jupiter?
3. How big is a 2x4 ("two by four") piece of wood?
Warning! These seem trivially simple,they're all easy to look up... and that's why they're interesting search challenges for this week. They don't take long to answer, but each one has a hidden gotcha.
Tell us what the answer is for each question, and WHY you think that's correct.
