Pokémon Ruby and Sapphire/Route 111

Route 111 is the path between ../Mauville City/ and both ../Lavaridge Town/ and ../Fallarbor Town/. You'll find that the route is blocked by rocks; you'll need to use Rock Smash to proceed. In addition, further north you will find a desert and a raging sandstorm, preventing you from passing through (and diverting you to ../Route 112/).

The Desert
Once you have the Go-Goggles (obtained after beating the Lavaridge Gym Leader), you can safely explore the desert. In the northeast corner of the desert is a pair of fossils. Grab one of them (the other will sink and disappear forever). Take it to the Devon Corp. and the researcher will determine it is a fossil of Pokémon. The researcher needs time to revive the Pokémon, which is in reality just a quick trip to and from the lower floor. The Root Fossil turns into a, while the Claw Fossil turns into an. These two Pokémon can only be otherwise obtained by trade or breeding.

Mirage Tower
In Pokémon Emerald, you will see a mysterious tower in the middle of the desert at times, and will probably realize soon after that the fossils are not where they should be in Ruby and Sapphire! To find them, grab a Mach Bike and enter this strange tower. Get to the top, and you can choose between the Root and Claw Fossil, as before. In Emerald, you can find the other fossil much later in the game. The tower appears occasionally when entering or leaving Route 111. If you leave the tower without obtaining a fossil, the tower will disappear, but visiting the Fossil Maniac on Route 114 will trigger the tower's appearance cycle again.

The Desert Ruins
At the very south end of the Route 111 desert, you will find a strange rock outcropping surrounded by six stones. This is the resting place of the Legendary Pokémon. As you'll soon notice, however, there is no entrance. The Desert Ruins will remain inaccessible until you solve the mystery of the Sealed Chamber. You'll be able to do this after you get your eighth Gym Badge. More details are available under Capturing the Regis.

The Winstrate Family
Hmm? There's a house next to this lake. And who's that standing in front of the entrance? It's the Winstrates!

The Winstrates are a family of four that offer a challenge to any and all passing trainers: beat all four in a row, and win a prize!

Defeating all four grants you access to their house, and talking to Victoria, the Mother, will net you a Macho Brace, which doubles all EV points gained from battle, while halving the holder's speed. Also, talking to the other Winstrates will reveal that there is actually a fifth member, the Brother, who is the strongest of them all. Perhaps you'll meet him someday on your own journey?
