## Overview
Located within South Dakota's Big Slough and Silver Lake ecosystems, the SkySpiral serves as an observation tower designed to enhance visitors' ecological and cultural interactions with the surrounding environment. The project embodies a contemporary architectural approach that integrates with the landscape while prioritizing functionality and user engagement. By offering a versatile observation experience, the SkySpiral aims to become a focal point for exploration and education within this natural context.

### Spatial Strategy
The SkySpiral features a spiral arrangement of observation platforms encircling a central mast, linked by a system of cable stays. This configuration optimizes the visitor experience by providing multiple viewpoints while maintaining a minimal land footprint. The structure's fluid form echoes natural growth patterns, such as plants or shells, creating a visual dialogue with its environment. The inclusion of an accessible ramp supports universal engagement, ensuring that visitors of all abilities can partake in the experience.

### Material Selection
The materials used in the construction of the SkySpiral reflect a commitment to sustainability and structural efficiency. Dimensional lumber forms the platforms, offering both warmth and stability, while high-tensile strength steel cables provide essential support with minimal visual intrusion. Additionally, cable mesh railings enhance safety without obstructing views. This thoughtful selection not only contributes to the aesthetic and functional qualities of the tower but also aligns with contemporary sustainable building practices through lightweight construction and reduced material usage.
