The drops aren't the greatest, but you do get lockpicks, tomes, alot of purples, and a few golds. The runs take about 8-10 Minutes depending on build you use, and there is only 10-13 Snow Wurms in the area, but 3 of them are usually near Pinesouls, which you should stay away from... unless you can get at them wurms without aggroing Pinesouls. Sometimes the Pinesouls spawn away from those 3 wurms, then your all set to get at them. Here is a map of the farming area: Area Map.jpg
You can also use your Norn Title if you need to for the extra health, mainly for melee builds.
================================================== =======
Here are some example builds I put together for farming these wurms: Some builds will be fairly quick, and others might be slow... But here are some faster builds. I just slapped these together, so they might not be the best or the quickest builds u can use against Snow Wurms... but its a start

================================================== =======
Ritualist: (Fast)
Vengeful Was Khanhei (Elite)
Pain Inverter
Vengeful Weapon
Lamentation
Essence Strike
Protective Spirit
Vampirism
Bloodsong
Template Code: OAOk8ohsISKkFjcJxDlzyU9gPY5E
Equipment: Basic 330hp equipment from my build. If want to know equipment, go to this link: 330hp Rt/Mo Vengeful Spirit Bonder
Usage: Find a spot where you can lay both spirits so they will attack the surrounding Snow Wurms. Mainly just try to get 3 Wurms within Earshot, then lay Spirits. Run into Melee Range, cast VwK, Pain Inverter, Vengeful Weapon, Lamentation, Essence Strike... and one should be dead. Energy usage is not bad, so you should have plenty to kill them off and regen up in between. There is no need for Spirit Bond, or any other enchants for farming these Wurms, so no worries.
Good thing about having the spirits is that they will still attack and do damage while the Snow Wurms are under ground.... it speeds things up a bit.
