Seems they are all adjacent to the east of the Rockies, although I did try Alaska first in case snow did not count.

Either east of the Rockies or in the rain shadow of the Cascades or Sierra Nevada (Great Basin states).

Also, Alaska has rainforests.

I tried Alaska, too, because the snow is pretty dry. However, I wasn't taking into account that southeastern Alaska is very rainy.

And surprisingly lush. There are drier and less...'jungly' places far further south, and it's all thanks to their many, many, many rivers.

The Tongass rainforest gets a lot of rain. Whittier, which receives 250 inches of snow and 200 inches of rain every year, is the wettest inhabited place in the nation. The coastal region is very, very, wet, wet enough to cancel out the dryness of the tundra.

Quiz should be renamed to "Western States that don't border the Pacific".

Right. Once you've figured out the area of the dry zone, all you need to do is name the states in the vicinity of it. 100%. :)

More accurately, 'Western states that don't border the Pacific, plus the Dakotas'.

Still less than 100 cm a year, which is barely even half of Hawaii's 178.5/yr., the wettest of them all. Seattle is surprisingly un-rainy for the stereotypes you'd hear. Much like London, it's more of a constant dull fog. A full 84% of Seattle's days (second from all major U.S. cities) is cloudy.

London's average annual precip (24.21 inches) is surprisingly close to Jerusalem's (21.81 inches).

London is the kind of place where it feels rainy even when the sun is shining.

It would be nice if this quiz was accompanied with a map where the states light up after you have guessed them, it is nice to see things in pictures rather than in words

(sorry for the almost childlike description of the last bit, atm my mind isnt cooperating to express myself more eloquently in english, so basic phrases will have to do, eventhough it doesnt truly make clear what I mean. Hopefully you understand the appeal of having a map included yourself.)

Agonising - I typed North Dakota just as the time ran out, and actually saw the full thing appear in the answer box, but it was too late...

Californias only 10? Guess our drought is more about all our people using the water we have than getting too little
