Load More goes to top of the page

I've got my mosaic post grid set up the way I like it, but when I click on Load More at the bottom, it refreshes the whole page and jumps back up to the top instead of using the ajax loading. The new posts are there when I scroll down, but it's not loading properly.
Here's the link to the page I'm building: http://pamelatakespics.com/blog/
