The Snows of Northrend

This guide only mentions the quests needed to get the achievement The Snows of Northrend, and is not an exhaustive list of Nesingwary quests. I would definitely advise doing others along the way to save you having to go back later and kill 60 game animals for example - only an idiot would do that...hello!

To get this achievement you need to do the following:

Start off at the Nesingwary Base Camp and speak to Weslex Quickwrench (25,58) to pick up Need an Engine, Take an Engine. Hand that in and pick up the follow-on quest; Have a Part, Give a Part. Also pick up Venture Co. Misadventure from Debaar (27, 59) also at Nesingwary Base Camp. Complete and return those 2 quests and then pick up the follow-on quest from Debaar, Wipe That Grin Off HisFace. Once handed in the next stage of the chain opens up

You can now pick up Rhino Mastery: The Test from Hemet Nesingwary (27,58), naturally at Nesingwary Base Camp, and Dreadsaber Mastery: Becoming a Predator from Buck Cantwell(26,59). Hand these in and you will be able to pick up Crocolisk Mastery: The Trial from Dabaar.

You will now have 3 quest chains on the go:
Debaar:

• 
  
• Crocolisk Mastery: The Trial
  
• 
  
• Crocolisk Mastery: The Plan
  
• 
  
• Crocolisk Mastery: The Ambush
• 
  
  

Hemet Nesingwary

• 
  
• Rhino Mastery: The Chase
  
• 
  
• An Offering for Soo-rahm
  
• 
  
• The Bones of Nozronn
• 
  
• Rhino Mastery: The Kill
• 
  

Buck Cantwell

• 
  
• Dreadsaber Mastery: Stalking the Prey
  
• 
  
• Dreadsaber Mastery: Ready to Pounce
• 
  

Complete these 3 chains to open up the next stage.

Pick up In Search of Bigger Game from Hemet Nesingwary, which is just a go and see someone quest.
Then pick up the following from Dorian Drakestalker (42,28), just west of the Savage Thicket - and conveniently the person Nesingwary sends you to see:

• 
  
• Securing the Bait
• 
  
• Sharpening Your Talons
• 
  

Once done, you can pick up Reagent Agent from Colvin Norrington and My Pet Roc and A Mammoth Undertaking from Zootfizzle. These three lead to Post –partum Aggression from Dorian Drakestalker.

Congratulations, you have now completed the achievement – and are probably sick of killing stuff - and if you're, not can I advise professional help.

This achievement is named after Ernest Hemingway's short story "The Snows of Kilimanjaro". (Hemet Nesingwary is an anagram of Ernest Hemingway.)

Actually, to get Post-Partum Aggression I only had to do the Mammoth quest, not the Reagent or Roc quests... Edit: Yup I just did the achievement by skipping "Reagent Agent" and "My Pet Roc"... those are optional :) The mammoth one is the only one you need from the last section.
