After playing with this for WAY too long, few youtubes and a bit of luck has lead to figure it out. Maybe I can save you guys a few hrs of headache, my way of paying back to a great wealth of information here.
First we need to be able to allow a google map on your site or blog. Google has gadget for that.

Now that that is done the part that stopped me in my tracks was figuring out how to get my ggogle earth map published online. After lots of failed ideas I just took the map and loaded it to Google Sites and picked up the link from there. This is a map I found online with all the shelters and descriptions.
https://sites.google.com/site/atnorthbounder/maps/AT w Shelters - Track Collection Filtered 200 Feet.kml?revision=1
So now its easy, open another browser page and go to the gadget link. Then copy and past the map link into the "my map url" section in the gadget. Adjust the size and border if you want. Then press preview, now press "get the code" and copy it. It should look like this.

Now go to your site or blog and in the html view paste it in. I have wordpress and it was as simple as pressing the html tab just about the text box ( next to visual)
The result: http://northbounder.com/?page_id=59
Have fun
