芝加哥几乎不知道它的山脉，所以沿着哈尔斯特德的高大的草山脱颖而出。
沿着许多路径之间的短暂步行揭示了一个不寻常的公园，一个草原流轻轻地流过布里奇波特层的历史。

在山前有一个洞。 芝加哥成立后几年，建筑蓬勃发展，石灰石，一种重要的建筑材料，开始在斯特恩斯站点采石场。 超过130年的采矿，洞穴变大，最终延伸至街道下方380英尺。

1970年，这个城市看了近期封闭的采石场，看到了一个方便的垃圾填埋场，用于建筑垃圾。 近三十年来，卡车堆放木材，砖，石头和焚化炉灰。 当倾销终于在20世纪90年代末期结束时，布里奇波特的公园空间数量翻倍。 这个想法出现在采矿和倾倒的最佳再利用之中。

Chicago is hardly known for its mountains, so the tall grassy hill along Halsted stands out.

A short walk down one of numerous paths reveals an unusual park where a prairie stream gently flows through layers of Bridgeport history.

STEARNS QUARRY

Before there was a hill, there was a hole. Just a few years after Chicago was established, construction was booming and limestone, an important building material, began to be quarried on the Stearns site. Over 130 years of mining, the hole got bigger, eventually extending 380 feet below street level.

TRASH TO TREASURE

In 1970, the city looked at the recently-closed quarry and saw a convenient landfill for construction waste. For nearly 30 years, trucks deposited wood, brick, stone and incinerator ash. When dumping finally ended in the late 1990s, an opportunity to double the amount of park space in Bridgeport presented itself. This idea emerged as the best re-use of the quarry and dump.
