Sorry to be skeptical but a ton of observations here end up not being 
satellites or rockets but instead end up being balloons and all kinds of 
stuff (I'm not saying this is a balloon).  So when someone says they 
"saw a rocket" the first thing we all think is "okay - he say's he saw a 
rocket but maybe it was just a cloud or maybe it was a weather balloon 
or an air plane or...".  I mean this happens to us so many times - 
people are absolutely sure they saw X when clearly they say Z.  I could 
give you a dozen examples.  In your case I don't know what you saw.  Yet.

A map is not helpful unless you were above looking down.

For example if a rocket was heading north east starting from the zenith 
that means it would appear to be headed downwards.  Towards the 
horizon.  it's  really hard to tell the difference between something at 
a relatively constant altitude moving directly away from you versus 
something falling to the ground.  If it appeared to be moving up it 
could actually be at a relatively constant altitude (or even falling) 
but coming towards you.

If you got any photos that would be great.  Any images you want to post 
just post them on drop box or imgur or a thousand other sites that are 
very helpful and then email a link to it onto here.  Did you see an 
exhaust plume separate from a rocket?  Was the plume larger than a 
point?  It should have been even from 100 miles away - even from 500 
miles away the plume should not be a point.  From 50 miles away you 
should be able to typically see some detail (rocket is shaped like a 
cylinder - or is larger at the leading edge).  Was there smoke 
afterward?  Typically you can see smoke for several minutes after.  
Particularly if it is hit by sunlight.

I guess it would be nice to know pretty much exactly what happened to 
make you think one stage ended and another started.

I can imagine rockets going absolutely straight up and then coming 
roughly straight down again (aka sounding rocket).  But heading "north 
east" into orbit from within 500 miles of Nevada is unheard of (I think 
it's unheard of - I could be wrong).  These rockets occasionally come 
crashing back down so you wouldn't likely see one heading in that 
direction from Nevada as it could land on someone.  Now from east coast 
that happens all the time as they are heading over the ocean where a 
failed launch landing in the ocean is unlikely to hurt anyone.  And from 
Vandenburg they can launch south or west.  Etcetera.

Launches are also published on the web.  And there are notams. You could 
check for a notam near Nevada (within 500 miles) for January 1 or 2.  
Even top secret launches usually have a notam and other information to 
be found on the web.  At least I was under the impression they did.  
Other's on this list know better than me.
