[Resolved, See Notes Inside!] Certain Level Needed To Explore Glacier?

I Currently Have 2 Wolves That Are Level 11, One Of Which Has 100% Scouting Proficiency, And The Second Has 98%. While They Were Able To Scout The Swamp Biome [A Challenging Area]. I Cannot Send Them To Scout The Glacier, Even With Full Energy, Due To "Not Having Enough Stats Or Energy" For The Location. Is There Any Way To Fix This?

I Recall Reading That The Glacier Requires High Wisdom To Scout, But Does Anyone Know How High It Needs To Be? Or If There Is A Way To Increase It?

Thanks In Advance! 

I don't think the exact stat gate is revealed anywhere, but the best way to increase stats right now is by re-scouting and level your wolves. 

Oof, Fair Enough. I'll Just Try to Grind Their Levels Up A Bit With Rescouting. Thanks For Your Reply! 

My girl Scout is able to explore there with Wisdom 122, though I believe the number is around 110.
