Pokemon trainers who are heading out for Memorial Day weekend or are taping a trip in the next week have the opportunity to embark on a geology quest.

In a news release, Pokemon announced an abundance of rock Pokemon will appear in Pokemon Go from now until June 5.

Below is the release from Pokemon.com.

Are you ready to get out and explore? Starting May 24, 2018, at 1 p.m. (PDT),Pokémon GO is kicking off two weeks of adventure that will have you rocking out as you explore your community. This event, which lasts through June 5, features a heavy emphasis on Rock-type Pokémon, so expect to come across many Pokémon like Geodude, Omanyte, Kabuto, Nosepass, Aron, Lileep, and Anorith.

In addition to all the special Pokémon that will be making appearances during this two-week event, other bonuses will be active as well. Buddy Pokémon will find Candy four times as fast while you’re out walking, and spinning the Photo Disc at a PokéStop or Gym will earn you extra XP—twice the XP for spinning a Photo Disc that you’ve already visited and a whopping 10 times the XP for spinning a new Photo Disc. You will even be given unique Field Research tasks during these two weeks, so don’t neglect your scholarly duties!

So lace up those hiking boots, grab your walking stick, pack plenty of water, and head out and make your own adventure with Pokémon GO!

Rock Pokemon are regarded as some of the most powerful and hardy Pokemon in the game, going back to the first generation of games when trainers had to face Brock’s Geodude and Onix in the first gym battle in Pokemon history. Each generation has had featured rock Pokemon make a splash in the core Pokemon games. 

While Rock Pokemon are weak against Grass and Water types, they are handy when it comes to battling Normal, Electric and Fire Pokemon. With Charmander being the featured Pokemon for the May Community Day, there’s a good chance trainers will face a Charizard when they travel to a gym. A powerful rock Pokemon will be a good way to dispatch a Charizard left in an opposing team’s gym.

During this event, trainers can expect rock Pokemon introduced in the third generation, including Aron, Nosepass, Anorith. They will also have the opportunity to capture rock Pokemon they may have missed in the earlier months. Pokemon like Kabutops and Omastar are a good combination of Rock and Water Pokemon.

Even if trainers are not into rock Pokemon, the event allows them to partake in the bonus experience points and new Field Research quests.

The rock Pokemon event is a good way to get trainers out and about during Memorial Day Weekend and in the days leading to Summer Vacation. The event is also a nice compliment to Pokemon Go announcing Articuno as the reward Pokemon for the Field Research quests in June.

After the Rock Pokemon event, there is a good chance trainers could see events for Water and Fire Pokemon during the summer.
