Roche-a-Cri State Park (from the French for ''crevice in the rock'') is a state park north of Adams and Friendship in central Wisconsin. The park, in area, was established in 1948. The park features a rock outcropping with Native American petroglyphs—the Roche-a-Cri Petroglyphs—and a wooden stairway to the top, as well as more than of hiking trails.〔(【引用サイトリンク】title=Roche-a-Cri State Park )〕 == Natural History == The striking bluff is a hard core that remains from a larger sheet of Cambrian sandstone which has mostly eroded away. Around 19,000 to 15,000 years ago it was an island rising above Glacial Lake Wisconsin. On top of the bluff grow red oak, black oak, white oak, red pine, white pine, and jack pine. Buzzards also haunt the top.〔(【引用サイトリンク】title=Roche-A-Cri State Park: Nature )〕 Image:Roche-A-CriRock.jpg|Outcropping rock Image:Roche-A-CriRHPSign.jpg|Sign File:Roche A Cri State Park Mound.jpg|The park from the south 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Roche-a-Cri State Park」の詳細全文を読む スポンサード リンク
