The subatomic level address for URL apparently is Microsoft's proprietary address for Everest. If you trim the coordinates back to 4 decimals (as you easily do with topozone) with Microsoft Expediamap the URL will not work (and did not work before). If you even changed the last subatomic digit even on point the URL would not work. So you could say that Microsoft has its own proprietary addresses for mountains. I knew they were into world domination but little did I know they were sending geeks with atomic calculators to summits too!
