Forward pinging with active sonar would give a return off an underwater mountain but subs if lucky will never ever, ever use active sonar. Might just as well take out a newspaper ad and tell the world where you are. The whole job of a sub revolves around not being detected and one ping with active sonar and every listening ship or sub within 50 miles will know where you are after your ping.

We navigate by accurate charts and good gyros that know exactly where we are. Every time this happens it's a pretty sure bet they were not where they thought they were.
