Well, the first idea is a poorly described SCP-055, and the second one has no story or draw. Also, this might be a nitpick of mine, but I personally don't enjoy Site localized anomalies, unless the Site was built around the anomaly. You don't get anywhere by saying most things are "unknown", unless the whole draw is why they are unknown. For articles that have a good story behind why things about the anomaly are unknown, I might suggest SCP-2740 (or SCP-055 again).
