Think before you type. Alot of people see the moon in the day. Full moon, while heavily linked to romance in our western culture, is not the beginning or end-all but rather a mid-point in the moon's monthly orbit. Sunsets are another time that people are out in the western world looking and that would be a good time to spot the crescent moon. As far as the part of the world facing away from the sun and the part facing the sun being seasonal - I think not...I think you're talking about day and night. It happens.
The seasons are mostly caused by the Earth's tilt.
Mostly? Be assured that they are caused by the earths' tilt. Here's a link to some long...really long...cycles that supposedly influence the seasons as well. We won't live to see these differences but I guess we can theorize about them and think about how they may affect us. What we're talking about here in this thread though seems to be something a little bit more abrupt.
(orbital distance and amount of landmass on the northern hemisphere that causes the north to experience more variant seasons than the southern),
Distance I know about but landmass I don't as far as a relationship to seasons. Please tell me more.
So as we've been saying, during the winter, the moon as viewed at night on Earth is going to follow the same general path through the sky as the sun does in summer
The moon follows the same path as the sun day and night, month after month with a variance of 5 degrees either side spread out over an 18.6 year cycle.
The moon is monthly, it is not seasonal. It varies 5 degrees from the suns' path over an 18.6 year cycle wherein it reaches maximum and minimum variance called lunar standstills and sometimes equated to the yearly solstices and equinoxes of the sun.
If you can draw a straight line from where the sun would be (below the horizon) through the boat moon to one of the constellations of the zodiac...I'll give you a guess what that means - and it's certainly not that there's something wrong with the moo[n]
Actually, a full moon is a mid point in the monthly phases of the moon, not necessarily a midpoint in its orbit. The phase of the moon is dependent on the relative positions of the observer on Earth and the sun at that time of year when compared to the moon's current position in its orbit around Earth.
And not to further derail, but yes, landmass is a factor in the seasons because the northern hemisphere has a lot more landmass than the southern and rocks, dirt, etc (aka 'land') is going to have a much more variant temperature between winter and summer than the oceans.
There is a smile moon on the equator because both the sun and the moon can be overhead there. They cannot be overhead in Las Vegas.
No. "Overhead" is irrelevant.
The Moon doesn't set when it is overhead.
There can be a smile moon whenever the ecliptic is nearly perpendicular to the horizon near moonset.
It happens frequently near the equator and less frequently the further from the equator you go.
The same effect occurs for the other situation, a "vertical" Moon. Near the poles it is a regular occurance, as you move toward the equator it becomes less common, at the equator it never happens.
Have seen many moons from 45 degrees north latitude and they were all within degrees of vertical. So gonna say no to that one too.

Yes.
Just as the boat moon is in within degrees of being perfectly horizontal.
Same situation. Rotated 90º. Just like the difference between the equator and the poles.edit on 2/29/2012 by Phage because: (no reason given)
You are not supporting your own argument.
The equator is at 0 degrees. Las Vegas is at 36 degrees north. It is much much closer to 45 degrees north than it is to the equator.
45º north latitude is farther from the north pole than Las Vegas is from the Equator.

The rest of your post...it's not a 2-dimensional world. The sun and the moon follow the ecliptic in the sky with variances as we have discussed. The sun is never (was never) overhead in Las Vegas because Las Vegas is at 36 degrees north latitude and the sun can only go (used to go) as far north as 23.5 degrees. The moon is never (was never) overhead in Las Vegas because the moon can only go (used to go) as far north as 28.5 degrees.
When you start in with the angles...I'm just going to say that in the past I never needed a ruler to verify that the moon was right for my latitude. Nitpicking doesn't make it right. There have been perfect boats in diverse latitudes that I have personally seen. We're well off the lunar standstill year now going down to minor whatever. This line of reasoning may have muddied the waters for me in 2006 but the boat moon (all the light at the bottom) has only escalated since then and this is 2012. And it's still on. In fact, it has now become a 'seasonal' event. Further, the explanations that I have read from you and others and 'official' sources all place the moon overhead at impossible latitudes. Side by side and up and down are 2-dimensional configurations.

Mongolia | Zaisan Tolgoi | Winter Solstice | 2009-2012
You are no doubt aware that the Winter Solstice is rapidly approaching. Here in Ulaan Baatar the solstice occurs at exactly 1:47 am on the 22nd....
Answer:
A careful observer will certainly notice that over the period of months, the crescent of the Moon does indeed seem to go from being lit on the "bottom" of the Moon to being lit on the side of the Moon. So what is happening to make the Moon look different? It is all a result of the Moon's orbit around the Earth, and the Earth's orbit around the Sun. And exactly when you see the Moon in the shape of a 'U' (lit on the bottom) rather than a backward 'C' (lit on the side) depends on what latitude you are at. But the explanation is the same regardless of when you see it from your location.
A superb image of a waning crescent Moon, in the early morning eastern sky of 4 September 2002. Note also the portion of the Moon lit up by Earthshine (sunlight reflected off the Earth and then onto the surface of the Moon). Also visible in the lower right corner of this photo are Jupiter, its 4 Galileo moons, and the Beehive star cluster.
