**History** The history of [Blendon Woods Metro Park](https://www.metroparks.net/parks-and-trails/blendon-woods/) began long before its 1951 opening, rooted in a landscape of rugged ridges and deep ravines that made the land unsuitable for traditional farming. In 1945, a report proposing a metropolitan park system for Franklin County specifically highlighted these cliffs of Bedford Shale as some of the "wildest land in the vicinity". Following this recommendation, the recently formed park district purchased the first 229 acres in early 1949. Because the terrain was so uneven, developers had to cut a mile-and-a-half-long roadway through dense woods just to bring in heavy equipment. This initial preservation effort ensured that the mature second-growth hardwood forests remained largely untouched by the urban expansion spreading toward Westerville. Opening day arrived on Labor Day, September 3, 1951, marking Blendon Woods as the second park in the Columbus and Franklin County Metro Parks system. The final push to open was a frantic race; the State Highway Department only finished the primary gravel access road four days before the gates opened. Early staff members, consisting of just four full-time employees, had to hand-dig pit toilets and learn construction skills on the fly to build the first picnic shelters. Despite the dusty conditions and limited facilities, the park was an immediate success, drawing massive crowds from across Central Ohio. By the end of the 1950s, annual visitation had already climbed to over 190,000 people. As the surrounding suburbs grew in the 1960s, the park faced severe overcrowding that threatened its natural habitats. In response, Franklin County voters passed the first Metro Parks levy in 1960, providing the funds necessary for a decade of steady expansion. During this era, the park nearly doubled in size, growing from 264 acres to over 570 acres by 1968. Planners also addressed a critical water shortage by collaborating with the U.S. Soil and Conservation Service to build a lake in 1964. This body of water originally served as a temporary reservoir before its role shifted toward conservation and wildlife support. The 1970s marked a transition toward the specialized wildlife and educational focus for which the park is known today. In 1971, the Walden Waterfowl Refuge was established around the 11-acre Thoreau Lake, creating a sanctuary that remains restricted to provide a quiet habitat for migratory birds. A formal nature center was also developed during this period, expanding on the guided Sunday walks that had been a park staple since the early 1950s. The park’s famous "Monarch Mansion" also became a prominent fixture, starting a long tradition of raising and releasing thousands of monarch butterflies each September. These initiatives cemented the park’s reputation as a premier destination for birders and nature enthusiasts. In more recent decades, Blendon Woods has continued to modernize while maintaining its wilderness character. The 10-acre Natural Play Area was added in 2017, encouraging kids to explore the ravines and woods off-trail. This was followed by the opening of a $1.5 million inclusive playground in April 2025, designed to accommodate children of all physical abilities. The nature center also underwent major renovations to include immersive, three-dimensional exhibits and a new butterfly house. Today, the park encompasses 653 acres, preserving a unique geologic and biological corridor amidst the bustling Westerville and Northeast Columbus area. **Map of the Park** Here is a map of [Blendon Woods](https://www.metroparks.net/wp-content/uploads/2025/05/BLN_map_Inclusive-Playground-and-Butterfly-Trail_May-2025_1980px.png). **Summary** For this event, we will hike the Lake View, Hickory Ridge, Ripple Rock, Overlook, Brookside, and Sugarbush Trails. This sounds like a lot, but it will really be only a little over five miles. Blendon Woods has a few hills here and there, but it's not one of the more strenuous metro parks. **Where We'll Meet** We'll meet just in front of the Nature Center. This is about a mile into the park from the main entrance. You have to go past the Ranger Station and the Shadblow Reservable Area to get to it, so don't stop too early at the Ranger Station and get it confused with the Nature Center. **After the Hike** Afterward, we will head over to [Forbidden Root Restaurant & Brewery](https://forbiddenroot.com/restaurants/columbus-ohio/) at Easton for [drinks](https://forbiddenroot.com/restaurants/columbus-ohio/#dinner-menu) and [food](https://forbiddenroot.com/wp-content/uploads/Cbus-Food.pdf). We should be there by 5 if you can't make the hike and just want to join us for drinks. The brewery's actual address is [4080 Worth Ave, Columbus, OH 43219](https://www.google.com/maps/place/4080+Worth+Ave,+Columbus,+OH+43219/data=!4m2!3m1!1s0x88388a86d10b6619:0x4d42b470a5cf11d3?sa=X&ved=1t:242&ictx=111); however, I recommend pointing your GPS to the [Worth Garage](https://www.google.com/maps/place/Worth+Garage/@40.0542293,-82.9137962,17z/data=!3m1!4b1!4m6!3m5!1s0x88388b4df6082825:0x17582f0eccd9dda1!8m2!3d40.0542293!4d-82.9137962!16s%2Fg%2F11rzfvvv8b?entry=ttu&g_ep=EgoyMDI2MDQxNS4wIKXMDSoASAFQAw%3D%3D) across the street. Parking in this garage is free as long as you're not on the first floor, and it is literally right next to the brewery.

Join us for a relaxed and enjoyable brunch at 17 Arrows Kitchen and Bar! This is a great opportunity to meet new people, enjoy good food, and ease into the weekend with great conversation. Whether you’re new to the group or it’s your first event, you’ll feel right at home.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
