i'm surprised no one has excused the deep cliffs and "desert" as a remnant from the Xindi weapon attack. (Yes, I know they attacked Florida...but hey -- why not stretch things out?)
And regarding the Narada -- I don't have a problem with Nero being captured and imprisoned -- it's the ship I have a problem with. Because there ain't no way the ship wouldn't be taken over by Klingons. I like to think they were just biding their time, and slowly making repairs (and trading for materials) until they rescued Nero. (The 47 ships being a response to the invasion that they were unprepared for). And THAt tome, could help me understand why so many ships were at Laurentia.
Being a mining ship, is it probable it had capability of embedding itself into an asteroid?
And the crew might have had some surviving scientist & military...but not enough to have a planned method of attack... they had enough knowledge to create a time warp...but not enough for the details.
Also, the decision must've been very spontaneous...like Spock arriving on the scene just after the disaster, and the Narada taking chase
