Two of my three EarthCaches were approved the day after I submitted them. I had to work with geoaware on the other to move my coordinates away from a Virtual that is in the area, but that's it. I may be in the minority, I know they are swamped right now.
It's all about working within the guidelines and making sure you are focusing on the geologic features of an area. A lot of my friends gave me ideas for EarthCaches that were marshlands, wildlife areas, reservoirs, etc. that had no geological significance, and I had to keep telling them to focus on the geology, not the ecology or biology of an area. Just my two cents.
